Abstract

842,547. Transistor amplifying and oscillating circuits. TELEFONAKTIEBOLAGET L. M. ERICSSON. March 19, 1959 [March 21, 1958], No. 9612/59. Class 40(6). An amplifier comprises a transistor which is driven to saturation by a rectangular waveform (Fig. 2A, not shown) applied to its base and whose collector circuit comprises a parallel resonant circuit 2, Fig. 1, tuned to the fundamental frequency of the rectangular waveform, in series with an inductance 3 shunted with a rectifier 4. A sine-wave output is taken from the parallel resonant circuit 2, the inductance 3 and rectifier 4 serving to maintain the transistor at saturation level throughout the periods during which the base is driven negative. In another embodiment, a pair of transistors are driven in push-pull from input transformer 31 and feed tuned output transformer, 21<SP>1</SP>, each acting as a rectifier shunting series inductance 3<SP>1</SP> when the other is conductive. The bases of the transistors are connected to the voltage source - V<SP>1</SP>cc via a voltage stabilizing Zener diode 8. Either of the arrangements described may be back-coupled to form a self-driven oscillator.
