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.

An offset 21 Jan 2021 The circuits design considerations including the comparator and asynchronous logic is illustrated in Sect. 4. Incorporating the techniques asynchronous ADC consists of a comparator, SAR logic block and two control blocks circuit compared to the comparator design and architecture.

A comparator to perform the function s(x i − x) by comparing the DAC's voltage with the input voltage. A SAR ADC uses a successive test algorithm to determine the voltage at an input node. As seen in the figure to the right, this includes a Digital to Analog converter(DAC). The DAC generates a reference voltage for a comparator which will test whether the input voltage is higher or lower than the voltage at the output of the DAC. The comparator is designed as a fully dynamic, simple and power-efficient one to save power and to reduce comparing time cost. 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.

SAR ADC design consideration A typical SAR ADC consists of three components: DAC, comparator, and SAR logic. It has become a superior ADC topology with a good tradeoff between power consumption, speed, and resolution.

simplicity and design specifications. SAR ADCs have a decent conversion speed (about 50kHz to 4MHz [13]) and take small overall chip area in comparison to flash ADCs, which are fast but take up a large area. SAR ADC design also flows well with the use of a serial output port due to the nature of the conversion method. SAR ADC is scalable with the technology scaling since most parts of the architecture apart from the comparator are digital. In this thesis, different structures of SAR control logics and dynamic latched comparators are studied; then, a 10-bit SAR ADC is designed and implemented in 65nm CMOS technology.
