  • Patent number: 8502603
    Abstract: A circuit includes a differential amplifier having a folded cascode architecture with a pair of cascode transistors. A sensing circuit senses a common mode input voltage of a differential input signal applied to the differential amplifier. A bias generator circuit generates a bias voltage for application to the pair of cascode transistors in the folded cascode architecture. The bias generator circuit is connected to an output of the sensing circuit such that the generated bias voltage has a value which is dependent on the sensed common mode input voltage. This dependence stabilizes a common mode output voltage from the differential amplifier in response to changes in the common mode input voltage.
