This paper presents a charge redistributed successive approximation register analog-to-digital converter (SAR ADC). Compared with the traditional Digital-Analog Convertor (DAC), the power consumption of the DAC scheme is reduced by 90%, the area is reduced by 60%. The test chip fabricated in 180 nm Complementary Metal Oxide Semiconductor (CMOS) occupied an active area of 0.12 mm 2 . At 10 MS/s, a signal-to-noise and distortion ratio (SNDR) of 57.70 dB and a spurious-free dynamic range (SFDR) of 55.63 dB are measured with 1.68 Vpp differential-mode input signal.

This paper presented a low-power Direct Digital Frequency Synthesizer (DDFS) using non-uniform sine-weighted digital-to-analog convertor (DAC). To avoid the need for a sharp filter to generate signals near and beyond the Nyquist frequency, parallel DACs, which cause to speed relaxation in a single DAC as well, and return-to-zero (RZ) technique were used. To reduce the area and power in parallel DACs, non-uniform sine-weighted DAC design method was proposed. This technique causes to reduce power consumption in DACs up to 48.47%, and nearly the same amount of reduction in the area. Meanwhile, by

A memristor element has been highlighted in recent years and has been applied to several applications. In this work, a memristor-based digital to analog converter (DAC) was proposed due to the fact that a memristor has low area, low power, and a low threshold voltage. The proposed memristor DAC depends on the basic DAC cell, consisting of two memristors connected in opposite directions. This basic DAC cell was used to build and simulate both a 4 bit and an 8 bit DAC. Moreover, a sneak path issue was illustrated and its solution was provided.

Sometimes, in some applications, such as in bioacoustics, it is necessary to convert digital data to analog signals with a special transformation that allows compressing and translating the spectrum toward audible frequencies. The process is called time expansion and can be conveniently achieved by slowing down the frequency clock of a digital-to-analog converter.

A digital-to-analog converter (DAC) in electronics is a device that transforms digital signals into analog signals. There are various DAC architectures, and DAC's usefulness for a given application is determined by factors like resolution, INL, DNL, power consumption, maximum sampling frequency, and others. Because digital-to-analog conversion may damage a signal, a DAC with negligible faults for the application should be used. The current-steered digital-to-analog converter is well suited for high-speed applications because no buffers are needed for current steering architectures and the outp

Sensors have a wide range of applications in environmental monitoring, for example, as temperature transmitters in industrial control processes. In order to reduce the chip area and improve the digital-to-analogue conversion accuracy, large loads are driven. This study proposes a current-shunted DAC for sensor interfaces with an R-2R structure, using a Class-AB amplifier to buffer or amplify the signal. Spectre simulation shows that the DAC has a current consumption of 63uA when the supply voltage and reference voltage are 1.8V and can drive a 15pF capacitive load.

In this work, the system-level design of noise-shaping (NS) successive-approximation (SAR) analog-to-digital converters (ADCs) is investigated and analyzed. It is shown that despite the fact that the NS SAR architecture shares the same fundamental NS principle with the ΣΔ architecture, there are a few implementation differences that imply different considerations for optimum system-level design, particularly in the selection of the system oversampling ratio (OSR) and consequent resolution of the associated digital-to-analog converter (DAC) for a certain target overall resolution. In addition,

Abstract— A probe system has been developed on the basis of an external ADC/DAC module (ADC is the analog-to-digital converter and DAC is the digital-to-analog converter). Using this system, it is possible to determine all the main plasma parameters of continuous and pulsed gas discharges. A program for the Windows operating system has been developed in C++ to control the probe system. The probe system can be used for diagnostics of plasma devices and can be included in modern microplasma analyzers of gas mixtures.

For precise digital control applications, high-resolution feedback is essential to achieve the required performance. Precise control systems with analog input-output and digital processing are generally limited by the resolution of digital to analog converter (DAC).

This paper presents a novel approach of combining two DACs to achieve higher resolution in closed-loop control systems.

An 11-bit 10 MS/s successive approximation register (SAR) analog-to-digital converter (ADC) is proposed for low-power and small-area applications. A 10-bit differential capacitor–resistor (C–R) digital-to-analog converter (DAC) is used to minimize the area of a DAC. The use of a C–R DAC reduces the capacitor area of a SAR ADC used CDAC by 75%. A capacitor calibration for the upper 5-bit capacitors of the C–R DAC is proposed to increase the linearity of the C–R DAC. To evaluate the proposed SAR ADC, an 11-bit 10 MS/s SAR ADC is implemented using a 180 nm 1-poly six-metal CMOS process with a sup

Sigma-delta modulator based DACs are simple circuits with low accuracy requirements in their analog components. However, their signal bandwidth is limited by speed constrains. Time-Interleaving allows the designer to trade-off between complexity and speed by replacing the original architecture by a number M of parallel paths clocked at a frequency M times smaller. The M digital outputs of the low-rate parallel paths are time multiplexed in a unique path at the high rate and converted to analog by means of a DAC. Unfortunately, this DAC must be also clocked at the high rate, it imposes severe r
