Oscillator-converter apparatus employing field effect transistor with neutralizationand square law operation

Claim 1

A MULTI-SIGNAL CIRCUIT HAVING, IN COMBINATION, FIELDEFFECT TRANSISTOR MEANS PROVIDED WITH GATE, SOURCE AND DRAIN ELECTRODES, A RELATIVELY LOW IMPEDANCE SOURCE OF ALTERNATING-CURRENT SIGNALS CONNECTED TO THE SOURCE ELECTRODE, A RELATIVELY HIGH IMPEDANCE SOURCE OF ALTERNATINGCURRENT SIGNALS CONNECTED TO THE GATE ELECTRODE, MEANS FOR PRODUCING SIGNALS SUBSTANTIALLY OUT-OF-PHASE WITH THOSE OF THE RELATIVELY LOW IMPEDANCE SOURCE, AND A NEUTRALIZING FEEDBACK PATH CONNECTED BETWEEN THE PRODUCING MEANS AND THE GATE ELECTRODE AND OF IMPEDANCE SUCH THAT THE OUT-OF-PHASE SIGNALS ARE SUBSTANTIALLY EQUAL IN AMPLITUDE TO THE SIGNALS FED FROM THE SOURCE ELECTRODE TO THE GATE ELECTRODE THROUGH THE INHERENT INTERELECTRODE CAPACITANCE THEREBETWEEN.
