SUPER-REGENERATIVE DETECTOR, SUPER-REGENERATIVE RECEIVER AND REMOTE CONTROLLER

摘要

PROBLEM TO BE SOLVED: To provide super-regenerative detection without increasing the number of elements and to simplify a circuit structure by amplifying a high frequency signal to output a super-rgenerative detection circuit, performing feedback input of an output of the super-regenerative detection circuit and undergoing low frequency amplification to output. SOLUTION: A super-regenerative detection 100 is provided with a broadened amplifier 60 on the preceding stage of a super-regenerative detection circuit 40. A high frequency signal which is inputted by the amplifier 60 is high- frequency-amplified and outputted to the circuit 40. An output of a low frequency signal which is undergone super-regenerative detection in the circuit 40 is performed a feedback input to the amplifier 60, and the low frequency signal is low-frequency-amplified in the amplifier 60 and outputted. Thereby, a low frequency amplifier which performs low frequency amplification of the output of the circuit 40 that is provided on the rear stage of the circuit 40 conventionally can be omitted. As a result, the detector 100 can consist of a small number of elements and also can acquire enough output level.
