Typical super regenerative radio receiver circuit diagram

The figure shows a typical super regenerative receiving circuit. The receiver can use a super regenerative circuit or a super heterodyne circuit. The super regenerative circuit has low cost and low power consumption of about 100uA. It has well-adjusted super regenerative circuit sensitivity and one-level high amplification, one-level oscillation, one-level mixing and two A mid-level superheterodyne receiver is almost the same. However, the super-regenerative circuit has poor operating stability and poor selectivity, thus reducing its anti-interference ability.
