Abstract
An integrated circuit R/C network and method for providing a selectively variable impedance in which a capacitor has a high resistivity semiconductor plate with a low resistivity body contact region therein, the contact region for providing a variable resistance in series with the capacitor, and in which a control terminal is connected to the plate for selectively applying a control voltage thereto which varies the series resistance to thereby vary the impedance of the network.
