ABSTRACT:
An improved superregenerative detector including input elements for receiving a high frequency carrier signal having an amplitude envelope upon which an information signal is impressed, the detector also including a first and a second oscillator and output elements for producing an output signal corresponding to the information signal. The detector features use of feedback components among the output elements, the feedback components including an operational amplifier and reference signal connected to the first and second oscillators such that the output signal of the operational amplifier may be used to constrain a transistor that defines the first amplifier to operate within its linear portion.
