A. c. operated transistor oscillator or amplifier circuits

Claim 1

TRANSISTOR CIRCUIT ADAPTED TO BE ENERGIZED BY ALTERNATING CURRENT COMPRISING A TRANSISTOR HAVING BASE, EMITTER AND COLLECTOR ELECTRODES, A PAIR OF ENERGIZING CURRENT INPUT TERMINALS, POTENTIAL DIVIDER MEANS CONNECTED DIRECTLY ACROSS SAID TERMINALS TO PROVIDE OPERATING POTENTIALS FOR SAID ELECTRODES, SAID POTENTIAL DIVIDER MEANS INCLUDING RECTIFIER MEANS AND RESISTOR MEANS IN SERIES WITH SAID RECTIFIER MEANS POLED TO CONSITUTE SAID POTENTIAL DIVIDER MEANS A VOLTAGE DIVIDER PROVIDING SAID POTENTIALS DURING THE HALF-CYCLE OF APPLIED ENERGIZING ALTERNATING CURRENT WHICH BIASES SAID TRANSISTOR FOR NORMAL OPERATING AND EFFECTIVELY TO OPEN-CIRCUIT WHEREBY THE REMAINDER OF SAID POTENTIAL DIVIDER MEANS SERVES TO CLAMP SAID BASE ELECTRODE TO THE SAME POTENTIAL AS SAID COLLECTOR ELECTRODE DURING THE REVERSE HALF-CYCLE, SAID BASE ELECTRODE BEING CONNECTED TO THE JUNCTION OF SAID RECTIFIER MEANS AND SAID RESISTOR MEANS, SAID COLLECTOR ELECTRODE BEING CONNECTED TO SAID RESISTOR MEANS, AND SAID EMITTER ELECTRODE BEING CONNECTED TO THE REMAINING SIDE OF SAID RECTIFIER MEANS.
