ABSTRACT:
A negative resistance device local extremum seeking circuit including a negative resistance device (NRD) and a biasing device for providing a bias signal to operate the NRD. The output of the NRD is detected by a detector that provides a signal which indicates the position of the bias signal in relation to the peak of the NRD. A bias adjust circuit responsive to the detector adjusts the bias signal toward the peak of the NRD to operate it at the peak.
