ABSTRACT:
A three terminal transferred electron device (TED) with a Schottky barrier gate and a series connected output circuit are connected to a bias supply which biases the TED just below threshold. A radio frequency (RF) signal of a given peak amplitude is applied to the TED gate which is biased such that the negative peak of each cycle of RF signal nucleates the domain in the TED. The resulting change in signal over a given time period at the output circuit is a measure of RF signal frequency.
