METHOD FOR INCREASING STABILITY OF WORK OF A SUPREGENERATIVE RECEIVER Russian patent published in 2019 - IPC H03G3/20 

FIELD: radio engineering and communications.

SUBSTANCE: invention relates to the field of radio engineering, in particular to regenerative and superregenerative amplifiers of radio signals. Method of changing the frequency of the generated pulses of a superregenerative receiver comprises the steps of: signal received by the antenna is fed to the resonant circuit; from the output of the resonant circuit, the signal is fed to the amplifier input; from the amplifier output, a positive feedback is fed to the amplifier input, damping oscillations are supplied there from the forced stall generator, the generation detector is constantly monitored by the generation, for which the generation detector compares the signals at the amplifier output and a decision is made on transition or exit to/from the generation mode, if the fact of generation is not detected, then the frequency of the forced stall generator is reduced; if the fact of generation is detected, then the frequency of the forced stall generator is increased until the generation stops.

EFFECT: increase the stability of the superregenerative receiver due to the dynamic change in the frequency of damping oscillations.
