Abstract
A superregenerative receiver includes a quenching oscillator for converting a received signal into a low frequency signal. The quenching oscillator comprises a transistor, a positive feedback circuit and an RC time constant circuit. A circuit is provided for modifying oscillation conditions including the base voltage of the transistor, a power supply voltage and the RC time constant of the RC circuit. In response to the output of the quenching oscillator whose oscillation condition or conditions have been modified, the quenching oscillator is placed into its optimum operating state in order that the receiver assumes substantially the maximum sensitivity.
