A precision op amp with +/-80 mA output current, 200 v/usec slew rate, and a gain-bandwidth product of 0.7 GHz

Thinh Ngo, R.K. Hester

Abstract

A three-stage operational amplifier has been designed and fabricated on a conventional process that achieves an unprecedented combination of performance for a precision operational amplifier. The amplifier provides high speed, wide bandwidth, precision DC characteristics, and high-output current drive capability. It also has the highest open-loop voltage gain and smallest chip size recorded for a precision op amp.>
