Abstract:
We present a parameterized method to design multivibrator circuits via piecewise-linear (PWL) chaotic systems, which can exhibit double-scroll oscillations. The circuit is conformed exploiting a parametric modulation that manipulates the equilibrium stability of each linear subsystem. Chua's oscillator is used as benchmark to illustrate the effectiveness of the proposed method to design multivibrator circuits. Thus, our proposal allows the design of the three configurations of a multivibrator: monostable, astable, and bistable. Potential applications are illustrated designing a pulse generator and a full S-R flip flop device based on our all-in-one multivibrator circuit.

Abstract:
This paper proposes a dual-mode controlled pulse width monostable multivibrator used for analogue signal processing applications that employs two differential voltage current conveyors (DVCCs), four passive components and an analogue switch. Unlike the traditional operational-amplifier-based monostable multivibrators, the proposed circuit contributes a dual-mode controlled scheme for adjusting the output pulse width through a voltage source and a grounded resistor. This paper discusses several previous designs and presents the circuit operations, related governing formulas, non-ideal effect problems, design considerations, and experimental examples of the proposed circuit. A prototype circuit was implemented, and commercially integrated circuits and discrete passive components were used to execute the experimental tests. The features of the proposed circuit are discussed, and the experimental results indicated that the circuit is feasibly used in dual-mode controlled pulse width for the output pulse and were consistent with those of the theoretical analyses.

Abstract:
The nonideal behaviour of astable multivibrators based on Negative Impedance Converter (NIC) type configuration is approached taking into consideration several nonidealities among which the slew-rate of the voltage operational amplifier (OA). Linear conversion of inductances, capacitances and resistances into time period is useful to measure impedances or physical quantities by means of impedance-type transducers. Following a series of investigations on this topic, a thorough study of four configurations for linear inductance-time and capacitance-time conversions based on the astable multivibrator viewed as a NIC-type nonlinear oscillator. Four circuits were studied, two of them having grounded reactive elements. The results can be used for linear capacitance-to-time (C|T) and inductance-to-time (L|T) conversions.

Pulse generation and distance adjustment between pulses is done through the microcontroller timer. A monostable multivibrator changes the pulse width of the microcontroller in the order of nanoseconds by adjusting the resistor-capacitor time constant which are done by adjusting the R value made from a digital potentiometer. The test results show that the microcontroller generates repetitive pulses with programmed intervals in order of 1 second and pulse width of 1.25 ms. A monostable multivibrator converts the pulse width to ca. 140 ns. Based on the test results, it can be concluded that the system functions according to the design as the system can generate repetitive pulses with pulse widths up to 140 nanoseconds with programmable interval and width parameters.

Full text
Abstract:
Parametric acoustic arrays are ultrasonic-based loudspeakers that produce highly directive audio. The audio must first be preprocessed and modulated into an ultrasonic carrier before being emitted into the air, where it will self-demodulate in the far field. The resulting audio wave is proportional to the double time-derivative of the square of the modulation envelope. This thesis presents a fully analog processor which encodes the audio into two Pulse Width Modulated (PWM) signals in quadrature phase and sums them together to produce a Single Sideband (SSB) spectrum around the fundamental frequency of the PWM signals. The two signals are modulated between 8% and 24% duty cycle to maintain a quasi-linear relationship between the duty cycle and the output signal level. This also allows the signals to sum without overlapping each other, maintaining a two-level output. The system drives a network of narrowband transducers with a center frequency equal to the PWM fundamental. Because the transducers are voltage driven, they have a bandpass frequency response which behaves as a first-order integrator on the SSB signal, eliminating the need for two integrators in the processor. Results show that the “SSB-PWM” output wave has a consistent 20-30dB difference in magnitude between the upper sideband and lower sideband. In simulation, a single tone test shows higher total harmonic distortion for lower frequencies and higher modulation depth. A two-tone test creates a 2nd order intermodulation term that increases with the frequencies of the input signals.

There are two kinds of this study: the first, the electromagnetic interference (EMI) in the Monostable, Bistable, and Astable multivibrator circuits are studied theoretically and experimentally. This experiment produces the electromagnetic field (EMF) by the form of a coil wound on a ferromagnetic toroid containing an air gap. The electromagnetic field influenced the conducting wire (CW) in the circuit, the experiment used an oscilloscope to measure the variation of circuit’s voltage and frequency by EMI, and used a spectrum analyzer analyzes the magnitude of the noise by EMI. The experimental and numerical results reveal that the magnitude of the EMI-induced noise is related to the pulse amplitude, the output load, the parasitic capacitance, the interference frequency and the interference amplitude. It is shown that a higher interference amplitude or frequency increases the harmonic noise. The second, the electromagnetic interference (EMI) in the light signal is studied the variation of the strength of light. This experiment produces the electromagnetic field in the tube by a coil on a solenoid, and influences the light signal of laser with a pulse wave. Using the PIN photodiode observed the variation of the pulse amplitude. The experimental and numerical result reveal that the magnitude of the EMF-influenced the strength of light signal is related to the number of the coil, the interference frequency and the interference amplitude. If the direction of EMI is inverse to optical path, that is shown a higher interference amplitude or frequency decreases the strength of light.

Abstract:
This thesis presents a novel current-controlled oscillator (CCO). It charges and discharges a source-coupled capacitor periodically with well-controlled current sources. Its current-to-frequency conversion relies on passive components, which are insensitive to the temperature and process variations. The proposed CCO is compact and area-efficient. Moreover, compared to ring-oscillator and LC-tank oscillator, it exhibits much wider tuning range and better linearity. Therefore, it suits the modern system-on-chip (SoC) design.

Abstract:
The reduction of the minimum feature size of an MOS transistor for digital VLSI circuits has been ongoing for the past few decades. As the channel length is scaled down into deep sub micrometer dimensions, the lower power supply voltage is required to ensure the device reliability. To be compatible with digital VLSI technologies, analogue integrated circuits, which can operate at low supply voltages, are also receiving significant attention. This has resulted in development of various current mode analog building blocks and operational transresistance amplifiers (OTRA) is one among those. The OTRA is high gain current input voltage output device, both the input and output terminals are characterized by low impedance. OTRA being a current mode building block inherits the advantages of current mode processing, the input terminals are virtually grounded leading to circuits that are insensitive to stray capacitances. Being a current processing device the OTRA has a bandwidth independent of the device gain and is also not slew limited in the same manner as an OP-AMP. Operational Transresistance Amplifiers are used in various type of applications namely filters, oscillators, multivibrators, multiplier and squarer etc. These all designs benefit from current mode approach of OTRA in this project a systematic review of the available literature on OTRA has been presented and are further studied and implemented. These OTRA based designs are best suited for the low power and high speed applications apart from its traditional field of application.

The present paper mainly applied a basic operation amplifier and a current mirror to the Bistable Multivibration Oscillator, as well, research and analyze to reduce the power consume. In this research, beside the topic of low power consume, the current mirror has been improved in order to reduce the area of layout. The software HSPICE of Synopsys Company is mainly used to design circuits and simulation. As well, in the circuit design, the Complementary Metal Oxide Semiconductor devises are offered by National Chip Implementation Center. Based on the 0.35μm regular processes of Taiwan Semiconductor Manufacture Cooperator, the Low Power Bistable Multivibration Oscillator has been designed. By the way of circuit simulation, the power consume largely reduced.
