Abstract
An electronic oscillation signal generation circuit includes an electronic oscillation circuit, a DC voltage source for providing a DC voltage to the electronic oscillation circuit, a switch for electrically connecting the electronic oscillation circuit to ground when the switch is turned on so as to generate an analog oscillation signal after the switch is turned off, a conversion circuit for converting the analog oscillation signal to a digital oscillation signal, a counter for generating a control signal when the digital oscillation signal reaches a predetermined number of periods, a delay unit for generating a delay signal a predetermined time after a falling edge of the digital oscillation signal is triggered, and a pulse signal generation circuit electrically connected to the counter and the delay unit for generating a pulse signal according to the control signal and the delay signal so as to turn on the switch.
