This circuit has a very high gain. When the signal is not received, it will generate special noise due to the influence of external spurious signals. The noise has a frequency range of about 0.3-5 kHz and sounds like a rustling sound. When a signal is received, the circuit resonates and noise is suppressed. The high-frequency circuit begins to oscillate. The speed of the oscillation is established and the length of the intermittent time is controlled by the amplitude of the received signal. The amplitude of the received signal is large, the initial level is high, the oscillation is established fast, and the intermittent time of each oscillation is short. The obtained control voltage is obtained. It is also high. On the contrary, the amplitude of the received signal is small, and the obtained control voltage is also low. This control voltage can be used as the output voltage of the circuit.
The super regenerative detection circuit is actually a high frequency oscillator controlled by intermittent oscillation. This high frequency oscillator uses a capacitor three-point oscillator, and the oscillation frequency is consistent with the reception frequency. The intermittent oscillation is generated in the process of high-frequency oscillation, which in turn controls the oscillation and interval of the high-frequency oscillator. The frequency of the intermittent oscillation is determined by the parameters of the circuit, generally from one hundred kHz to several hundred. Kilohertz, low frequency, good anti-interference ability, but low sensitivity, high frequency selection, just the opposite.
