Design Considerations and Evaluation of a High-Speed SAR

Systems that are powered by non rechargeable batteries such as medical implant devices require low power design. This system uses Analog to Digital Converter (ADC) as an interface between analog and digital domain. This paper presents a low power comparator used in designing of Successive Approximation Register (SAR) ADC. A simple topology of 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.

The comparator in the SAR ADC takes more power consumption than other blocks. In SAR ADC we must design comparator such that it consumes very less power. A comparator generates a logic output high or low based on the comparison of the analog input with a reference voltage. For power optimization the supply voltage of SAR ADC is designed with 500 mV.
