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.
