Abstract
A monolithic microwave oscillator using a negative resistance cell includes a resonator, a negative resistance cell that employs an active device, an output buffer for voltage and current amplification, and a field effect transistor. The negative resistance cell includes a bipolar junction transistor as its active device, with the output buffer circuit coupled to a base of the BJT through the field effect transistor. The combination of the resonator and the negative resistance cell produce a periodic RF microwave signal that is sampled, amplified and buffered by the buffer circuit without degradation.
