Methods and apparatuses for superregenerative system are disclosed, including an oscillator circuit for a superregenerative receiver. The oscillator circuit includes an RF oscillator, incorporating a self-biased transistor and a positive feedback circuit; and an external quench oscillator, for providing a quench signal to the RF oscillator; wherein the quench signal is coupled to the RF oscillator through a reversed-biased diode. The arrangement improves the performance of conventional superregenerative receivers by providing high selectivity and optimum receiver sensitivity, which is insusceptible to variations in supply voltage, temperature and device parameters. |
