Method for enhancing the starting of an oscillator of a super-regenerative receiver, and receiver for implementing the method

A method for enhancing the detection of the start time of a reference oscillator (4) of a super-regenerative receiver (1), the receiver (1) comprising the reference oscillator (4), a bias current generator (7) for supplying a bias current (i_vco) to the reference oscillator (4) on receiving at least one activation control signal (Sosc), an oscillation detector (6) connected between an input or an output (coilp) of the reference oscillator (4) and the bias current generator (7) for detecting an oscillation in the reference oscillator (4), and an impedance matching unit (3) disposed between a terminal or pad (2) for receiving an RF signal of the receiver (1) and the reference oscillator (4), the method comprising:

• following the supply of the bias current (i_vco) after receiving the activation control signal (Sosc), the oscillation detector (6) detecting a first oscillation of the reference oscillator (4) to enable the additional amplification generation circuit to be activated and supply the additional amplification current dependent on the envelope of the oscillation detected at the oscillator, and the oscillation detector (6) supplying a stop control signal of the reference oscillator (4) after the second detection of oscillation with amplification of the oscillating signal,
• wherein at each activation control signal (Sosc) supplied to the bias current generator (7), a bias current which increases progressively until at least one critical current value is attained from which the oscillation of the reference oscillator (4) starts, wherein the oscillation detector (6) detects the first oscillation of the reference oscillator (4), and
• wherein at the second oscillation detected by the oscillation detector (6) a stop control signal (stop) is supplied to the bias current generator (7), as well as an additional amplification current generation circuit for immediately cutting off the supply of the currents to the reference oscillator (4) to stop it immediately and thus reduce the electricity consumption of the receiver.
