  • High gain rail-to-rail CMOS amplifier
    Patent number: 5337008
    Abstract: A CMOS operational amplifier input senses a rail-to-rail differential voltage and provides an amplifier rail-to-rail single-ended output voltage. A first P-channel input section sources a first differential signal current that is proportional to a first portion of the input voltage, and a second N-channel input section sinks a second differential signal current that is proportional to a second portion of the input voltage. The first and second differential currents are combined in a folded cascode gain stage to produce an intermediate single-ended voltage that is not rail-to-rail. The single-ended intermediate voltage is converted to a rail-to-rail output voltage in a current-limited rail-to-rail output section.
