1. a kind of amplitude limiting oscillation circuit, it is characterised in that include:

  • Oscillating circuit (110), for producing oscillator signal;

    Pulse width modulation circuit (120), for the amplitude according to the oscillator signal, produces pulse width modulating signal;

    Low-pass filter circuit (130) is for the pulse width modulating signal is converted to direct-current control voltage signal, described straightFlow control voltage signal is used for controlling thyrite circuit (140);

    Thyrite circuit (140), for the control according to the direct-current control voltage signal, changes the thyrite circuit(140) resistance value, to control the amplitude of the oscillator signal.
