Abstract

This thesis project involves the design and analysis of an 8-bit Successive Approximation Register (SAR) Analog to Digital Convertor (ADC), designed for low- power applications such as bio-medical implants. The sampling rate for this ADC is 500 KS/s. The power consumption for the whole SAR ADC system was measured to be 2.1 uW. The novelty of this project is the proposal of an extremely energy efficient comparator architecture. The result is the design of a final ADC with reasonable sampling speed, accuracy and low power consumption. In this project, all the different subsystems have been designed at the transistor level with 45 nm CMOS technology. The logical circuit was designed using Verilog language. It was then synthesized and integrated in the overall system.
