| 20140369531 | SELF-BIAS EMITTER CIRCUIT - Self-bias emitter circuit configurations can use the amplitude of an input AC carrier signal to provide a DC bias voltage across an emitter for suitable operation. A self-bias emitter circuit can include a transductor with primary matched with an amplifier, while secondary can be matched to the emitter. Self-bias emitter circuit can also include a full-wave bridge rectifier or a center tap inductor in conjunction with two diodes to rectify the AC carrier signal into a corresponding DC voltage. This DC voltage can be subsequently filtered by a capacitor to provide a steady DC bias voltage across the emitter. Sufficiently small, decoupling capacitors can be installed at each side of the full-wave rectifier in order to decouple the DC bias voltage, while a sufficiently large capacitor can be installed between the emitter and secondary for preventing the applied DC bias voltage from flowing back to secondary. | 12-18-2014 |
