Abstract:
An RF superregenerative circuit operable in at least a receive mode of operation, comprising:(A) a superregenerative oscillator having an oscillator output, said oscillator including an amplifier having an input and an output, a resonant circuit arrangement connected to said output of said amplifier, and feedback means connecting said resonant circuit with said input of said amplifier; (B) circuit means for controlling the oscillatory condition of said oscillator; (C) antenna means; (D) decoupling means connected in circuit between said antenna means and said oscillator and operable to minimize any RF energy radiated by said superregenerative circuit, via said antenna means, when in said receive mode of operation; (E) utilization means connected to said output of said oscillator; (F) said circuit means being operable to provide said oscillator with, periodic signals to allow oscillation thereof; and wherein (G) said utilization means includes timing circuitry operable to measure the time difference between the time that said circuit means allows oscillation and the time that the magnitude of said oscillations attain a predetermined reference level.
