Abstract:

The performance of the power amplifier is closely related to their hardware components and current control modes. The work was focused on comparison of the experimental results based on different current sensors and the application of two different current control modes for 3-state amplifiers. When the same control mode was used, three kind of current sensors were tested and the corresponding amplifier current ripples were measured. Experimental results shown that when using a faster current sensor, the amplifier achieved smaller current ripples. Then a 3-state PWM current control mode and a S

Abstract:

Despite excellent high frequency and high speed performance, current-feedback operational amplifiers (CFOAs) generally exhibit poor common-mode rejection (CMRR) properties, which limit their utility [Analogue IC design: The current–mode approach, IEE Circuits and Systems Series, Peter peregrinus, 1990]. A novel current feedback operational amplifier (CFOA) with improved performance is presented.

This paper presents an analysis of a reconstruction filter in a switched mode power amplifier system. Doubly and singly terminated filters for current-mode class-S power amplifiers were analyzed previously through analytical, numerical, and experimental approaches, and it was shown that only singly terminated filters can fulfill the requirements of current-mode switching amplifiers, owing to their constant input resistance over the pass-band. In this paper potential effects of the parasitic components in the actual filters and the filter termination are evaluated. The simulation and measuremen

Abstract:

This work presents a comprehensive theoretical analysis of current-mode power amplifiers as a function of input power for different biasing classes under the common simplifying assumption of constant transconductance and hard current cut-off/saturation. Typically, the theoretical analysis of power amplifier performance and behavior are carried out only at maximum output power. However, to achieve high data-rates, modern telecommunication systems adopt signals characterized by a very high peak-to-average power ratio, thus it is useful to analyze the power amplifier behavior as a function of pow

MTCMOS (Multi-Threshold CMOS), sleepy stack, sleepy keeper, and footer stack are examples of low power saving techniques incorporated into the core gpdk 90nm technology papers used in the proposed study using Cadence. The main focus of these tests is the power consumption of various sense amplifier circuits. The simulation results show that the charge-transfer sense amplifier uses much less energy than voltage and current sense amplifiers. The present mode detecting amplifier’s power consumption can be decreased by up to 98 percent by using MTCMOS technology.

Abstract:

This study introduces an electronically tunable resistorless mixed-mode universal filter and dual-mode quadrature oscillator configuration utilizing merely two voltage differencing gain amplifiers and two grounded capacitors. The suggested filter can perform all generic biquadratic filter functions in all four modes: voltage mode, trans-admittance mode, current mode, and trans-impedance mode, while utilizing the same design. The pole frequency and the quality factor can be tuned electronically and orthogonally by means of the transconductances of the voltage differencing gain amplifier. The du
