Simulation design and test of automatic gain resonant circuit of vibration cylinder sensor
Based on characteristics of variable resistance region and the central break region of junction field effect transistor(JFET),the automatic gain resonant circuit of vibrator cylinder sensor is simulated and tested.The relationship between the duty ratio of excitation signal and the electrical characteristics of vibration cylinder,implementation mode of automatic gain control resonant circuit and design idea of the waveform,amplitude and duty ratio of the output signal at the excitation end of resonant circuit are discussed emphatically.By designing the excitation signal waveform,amplitude and duty cycle of the vibration cylinder,the stability of the sensor and the quality of the output signal are improved effectively.
