Abstract

1,004,491. Transistor oscillator circuits. LICENTIA PATENT VERWALTUNGS G.m.b.H. June 14. 1962, No. 22931/62. Heading H3T. In a push-pull oscillator circuit the base bias voltage of the transistors 1, 2 for starting oscillations is derived from a starting resistor 10 connected in series with a D.C. source 9 and a diode 11 as shown in the Figure, the diode 11 being poled to oppose current flow from the source.
