Abstract
A BIMOS amplifier having feedback clamping the amplifier's input to a predetermined voltage, minimizes input signal voltage excursions in the presence of large load capacitances. A pair of differentially coupled NPN transistors in response to first and second inputs drive a pair of emitter follower NPN transistors. First and second MOS transistors responsive to first and second enable signals are coupled between the ouptut from each of the emitters of the emitter follower transistors and the first and second inputs, respectively.
