ABSTRACT:
The present invention is a high speed, low gain stable amplifier. The amplifier is for amplifying an input signal and providing an output signal to a known, fixed load. The amplifier has a first stage that is a differential amplifier that amplifies the input signal. The amplifier then has a second stage which is a push pull transconductance stage which operates at a low gain (approximately unity gain), and the transconductance of the push pull transconductance stage is approximately equal to the reciprocal of the impedance of the predetermined load. The push pull transconductance stage includes first and second driver transistors. These driver transistors control the output signal. The amplifier of the invention provides amplification of a wide bandwidth with minimal phase shift.
