Abstract: Together with the increasingly demanding DAC, the design of the comparator introduces a big challenge for the implementation of high resolution SAR ADCs. Therefore, several state of the art works investigated improved comparator architectures aiming for higher resolution. Charge Redistribution SAR ADC • 4-bit binary-weighted capacitor array DAC (akacharge scaling DAC) • Capacitor array samples input when Φ 1is asserted (bottom-plate) • Comparator acts as a zero crossing detector • Practical implementation is fully-differential Power 8-Bit Asynchronous SAR ADC Design Using Charge Scaling DAC," 2014 Fifth International Symposium on Electronic System Design, Surathkal, 2014.

Sonoli, "Design and simulation of 10-bit SAR ADC for low power applications using 180nm technology," 2016 International Conference on Electrical, Comparator based ADC design : SAR ADC. 2011.06.18 A. Matsuzawa，Titech Basic idea for low energy analog design 16 d DD s DD L s togle P V I V C I f The clocked comparators fit well into a SAR because the SAR is a clocked system. Since you are looking at using the SAR for calibration, you are not really aiming at speed and I guess you can afford to add autozeroing to your clocked comparator. reason, the group decided to use the SAR architecture for its 65nm ADC. This thesis describes the design port of a comparator for a SAR ADC in digital still camera and camcorder applications, from the 65nm to 0.11pm process node. The two processes have similar characteristics and both operate off a 1.2V supply.

Figure 1. Top block diagram of the DSRC receiver. Successive approximation register (SAR) ADC architecture has been a very popular architecture for many applications, as it features the CMOS do wnscale size [6 8]. SAR ADC does not require any the dynamic comparator is chosen for the SAR ADC. The sampling switches are bootstrapped to reduce the non-linearity introduced when the input signal is 5 Dec 2017 The comparator was designed for 12-bit 1.6MS/s Successive Approximation Register (SAR) Analog-to-Digital Converter (ADC). An offset 21 Jan 2021 The circuits design considerations including the comparator and asynchronous logic is illustrated in Sect.
This paper is going to address the design challenges and strategies of low power ADCs for biomedical implant devices. The comparator in the SAR ADC takes more power consumption than other blocks, in this paper low power comparator is designed for reducing power consumption in SAR ADC.

The digital SA logic module is an asynchronous module, which is fine designed to reduce the number of data flip-flops in the critical control path, so as to cut the logic time down. V. T. Fiutowski ADC SAR layout considerations 10-bit SAR ADC in 130nm IBM •Simulated ENOB ≈ 9.5-9.7 bits •Maximum sampling rate ~50 MS/s •Power consumption ≈ 1-1.4mW @ 40 MS/s •Slightly different DAC capacitance splitting in 2 prototypes •No dummy capacitors in DAC network! Two ADCs designed in 130nm IBM The SAR ADC consists of a sample-and-hold circuit, a comparator, a DAC, SAR logic and a timing generator (Fig.1). Conversion of the SAR ADC is based on principle of balance and generally it uses the binary search algorithm. Firstly, the sample-and-hold circuit acquires analog input voltage.
