Design of High Slew Rat and low offset and low driftAmplifier in 180nm SCL technology: Theoperational amplifier (op-amp) is a criticalcomponent in analog and mixed signal designapplications. Among all parameters of op-amp slewrate is a critical parameter in the design. The outputof an operational amplifier should follow the inputirrespective of any conditions, but this does nothappen at high frequency. The slew rate of an opampis very less at high frequency. The design ofHigh Slew Rate Amplifier should cater thesefeatures in Junction temperature range -40 °C to+125 °C: Slew rate 1200V/?sec, UGB >200MHz, Input Open Loop gain> 80dB, UGB > 100MHz, Offset 75?V Max, input offset<100?V, Low Drift 1.3?V/ºC.
