Abstract
A negative shunt feedback CMOS amplifier is disclosed for connection to the output nodes of MOS interchip digital signal receiver differential amplifiers which have highly capacitive output nodes in order to bypass the large capacitance to thereby extract a high speed current signal. A first embodiment of the invention uses a resistor as the shunt feedback and a second embodiment of the invention, to which this application is directed to, uses parallel N-channel and P-channel FETs to form the shunt feedback impedance.
