Abstract:
1. A feedback oscillator device formed with an integrated circuit, said device comprising: a semiconductor material substrate having a conductive ground plane on an equipotential major surface thereof on a side opposite an operating major surface thereof; an amplifier having an input and an output provided at least in part on said semiconductor material substrate at said operating major surface thereof, said amplifier being capable of providing signals at said output thereof representative of signals occurring at said input thereof; a coupler having an oblong input conductor of a selected input length provided on said operating major surface of said semiconductor substrate electrically coupled at one end thereof to said amplifier output, and further having an oblong output conductor of a selected output length provided on said operating major surface of said semiconductor substrate closely adjacent to said input conductor with said input conductor over said input length being substantially parallel to said output conductor over said output length, said output conductor being electrically coupled at one end thereof to said amplifier input; and a capacitor electrically coupling said coupler output conductor through said capacitor to said amplifier input.
