  • Oscillator amplitude regulating system
    Patent number: 3973220
    Abstract: The disclosure relates to an amplitude control for controlling the peak amplitude of a transistor oscillator output alternating voltage and to an improved regulating system which includes an oscillator associated with the amplitude control for converting a DC voltage to an alternating output voltage having a regulated or controlled peak amplitude. The amplitude control comprises a control voltage generating means for providing a control voltage and clipping means coupled between the base of the oscillator transistor and the control voltage generator for varying the bias of the oscillator transistor responsive to the control voltage to thereby control the peak amplitude of the oscillator alternating output voltage.
