Circuits with low power and low voltage operation are considered mandatory for biomedical applications in order to strengthen the system for longer life and less power consumption. Therefore, selecting the right ADC (Analog-to-Digital Converter) architecture is very important. This thesis is an extensive presentation of the structure and the operation of ADCs, analog to digital converters and studied design of analog circuits for Successive Approximation ADC for biomedical applications in CMOS technology. Design techniques and specifications are presented depending on the intended application and these differences make each ADC implementation unique. Specifically, low power consumption, speed, accuracy, and low cost of construction is one of the criteria we've addressed in this paper. The main part of the thesis is the design of the comparator (Comparator), the operational amplifier and DAC (R2R Ladder with MOSFET) at 180nm CMOS technology, using the electronic design automation software CADENCE DESIGN SYSTEM in conjunction with the EKV3 MOSFET compact model. The designed circuits show results comparable to existing implementations giving incentive job progress.
