    摘要: A super-regenerative receiver including a super-regenerative oscillator is disclosed. The super-regenerative receiver includes a super-regenerative oscillator for generating an oscillation signal when receiving driving current exceeding a predetermined critical level. The receiver also includes a bias current controller for generating bias current according to an output of the super-regenerative oscillator, and a pulse width controller for receiving a predetermined clock and controlling a width of the clock according to the output of the super-regenerative oscillator. The super-regenerative receiver further includes a quench generator receiving the width-controlled clock from the pulse width controller and generating quench current that varies according to the pulse width of the clock. The driving current for oscillation equals to a sum of the bias current N-times multiplied and the quench current.
