  • Driven-common electronic amplifier
    Patent number: 5121079
    Abstract: Sampled input, common mode driven, differential amplifier. Both inputs to a differential amplifier are sampled with a high input impedance amplifier. These signals are then summed and used to drive a buffer amplifier. The output of the buffer amplifier then drives the floating common node of a floating power supply. The floating power supply powers the main differential amplifier.
