A Fast Settling FET Input Monolithic Instrumentation Amplifier

An Instrumentation Amplifier is described which achieves a gain-bandwidth product of 400 MHz at a gain of 1000 while remaining stable at unity gain. It also features FET inputs making it highly useful in multiplexed acquisition systems. The circuit is built on a Bi-FET/Thin Film bipolar process with no special high speed requirements.
