Abstract
A method is provided for enhancing the detection of the start time of a reference oscillator () of a super-regenerative receiver (), which includes the reference oscillator, a bias current generator (), an oscillation detector (), and an impedance matching unit (). Following the supply of the bias current (i_vco) after receiving the activation control signal (Sosc), an oscillation detection is performed by the oscillation detector (), and once oscillation is detected, an additional amplification current (iboost) dependent on the envelope of the detected oscillation, of an amplification current generation circuit is supplied to the reference oscillator () in addition to the bias current to amplify the oscillation signal to be above a critical oscillation start threshold so as to precisely define the start time of the oscillator, and enable the oscillation detector () to order the stoppage of oscillation of the reference oscillator ().
