VLSI is a field of electronics engineering which aims to reduce the size of the device by putting millions and billions of transistors logically together on to a single chip. VLSI opens a way to create power efficient, portable, low cost and environment friendly circuits. Modern electronic world is completely digitalized and there is a necessity to convert all the analog signals to digital for further processing. Sample and hold circuit plays a vital role in analog to digital conversion. Current conveyor analog Switch (CCAS) is a better solution for the digital world as it offers high speed and less power dissipation when comparing with existing sample and hold circuits. The paper presents the design of Successive Approximation Register (SAR) analog to digital conveter with the help of CCAS. The functional verification is done with the help of Mentor Graphics Tool. The obtained results matching with the expected ones show that this will be an efficient solution for analog to digital convertor design.
