Abstract

Complementary metal–oxide–semiconductor (CMOS) is a technology for constructing integrated circuit. CMOS technology is used in microprocessors, microcontrollers, static RAM, and other digital logic circuits. CMOS technology is also used for several analog circuits such as image sensors, data converters, and highly integrated transceivers for many types of communication. Metal-oxide- semiconductor -field -effect -transistor is a device used for amplifying or switching electronic signals. In MOSFETs, a voltage on the oxide-insulated gate electrode can induce a conducting channel between the other two contacts called source and drain. The popularity of a folded cascade mostly comes from the flexible input common mode level and the availability of shorting the input and output together even though it consumes higher power and requires more complicated design. Regarding to project applications, the noise coming from the input signals will affect both signal paths. The noise that affects both input paths are identical and will be rejected by this differential characteristic. In this project,will SILVACO EDA tool will be used to design the layout and schematic of folded cascade operational amplifier (Op-Amp). Both of them must be equivalent in the validation step before proceed to fabrication process.
