Abstract :
This paper describes the design of a CMOS based low voltage op-amp. The low voltage op-amp can be operated with supply voltage of 1V. It has unity-gain bandwidth of 18 MHz without compensation and slew rate of 25V/μs with 10pF capacitive load. A compensation network has been implemented, which enables the op-amp´s unity-gain bandwidth to increase till 24 MHz. Under no load condition, it gives a bandwidth of 576 MHz. All of the simulations in this project are using 0.8μm CMOS technology.
