Abstract :
An operational amplifier (Op Amp) based on self cascode structure is proposed that works with a supply voltage of ± .75 volt. It provides an open loop gain of 52 dB with a unity gain frequency of about 17 MHz, with 145 microwatt of power consumption. Simulation results are based on p-spice simulation for 0.25 ¿m CMOS technology.
