Abstract
An improvement to an implantable amplitude modulated frequency receiver wherein a resistor in the demodulator portion of a prior art receiver, which provides a discharge path for a capacitor, is replaced with an active circuit portion that includes a semiconductor device that provides the discharge path wherein the conductivity level of the semiconductor device is inversely related to the level of conduction of a rectifier to which the received amplitude modulated signal is applied. The active circuit portion improves the efficiency of the receiver in that less power is lost than in the case of the resistor the active circuit portion replaces.
