ABSTRACT

Operational Amplifier (Op-Amp)

integreted circuit with 1.5 I-' CMOS Tech­

nology has been designed. A systematic

design approach which can be applied for

designing various types of analog circuits

has been presented. The designed Op-Amp

has specifications as follows. It is a Si Gate

N-well process with power supply of '" 5 V.

open loop gain> 50,000, drain current < 200

I-'A. input impedance > 100 MQ , output

impedance < 500Q. bandwidth> 1 MHz and

having slew rate> 1 V/I-'sec.
