  • Gm-C cell with two-stage common mode control and current boost
    Patent number: 5963084
    Abstract: A gm-C circuit includes a two-stage common mode control loop to limit the common mode voltage during circuit operation. To prevent latch-up in a cross-coupled differential gm-C type filter, the common mode control loop includes a circuit which provides extra current capability to the common-mode control loop without increasing the quiescent, current. This is accomplished by a current boost technique that provides large amounts of current when needed, while running in a low current mode under normal circumstances.
    Type: Grant
    Filed: August 31, 1998
    Date of Patent: October 5, 1999
