Abstract
A method for detecting an RF signal detected by a super-regenerative receiver (). The receiver includes a reference oscillator () for generating an oscillation in the oscillator, a bias current generator () for supplying a bias current, an oscillation detector () connected between an output (coilp) of the oscillator and the bias current generator for controlling when an RF signal is received by the receiver, and an impedance matching unit () disposed between the input of the receiver and the reference oscillator (). Following activation of a start control signal, detection of the oscillation of the reference oscillator is performed, and once the reference oscillator oscillates above a critical increasing bias current value, the oscillation detector orders the bias current generator to cut off the bias current and thus stop the oscillation of the reference oscillator to reduce the overall electricity consumption during an RF signal detection phase.
