Patent ID: 8299832

Claim:
An electronic oscillation signal generation circuit comprising: an electronic oscillation circuit; a DC voltage source electrically connected to a first end of the electronic oscillation circuit for providing a DC voltage to the electronic oscillation circuit; a switch for electrically connecting a second end of 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 electrically connected to a second end of the electronic oscillation circuit for converting the analog oscillation signal to a digital oscillation signal; a counter electrically connected to the conversion circuit 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.
