INFRARED REMOTE CONTROL RECEIVER HAVING SEMICONDUCTOR SIGNAL PROCESSING DEVICE DESIGNED WITH ONLY CMOS PROCESS

摘要

The present invention is a semiconductor which relates to an infrared remote control receiver, receiving the signal from the photodiode, a photodiode for converting an optical signal into an electric signal to remove noise components and generates a pulse signal that corresponds to the remote control signal received from the transmission system, signal processing apparatus, and decrypting receives the pulse signal from the semiconductor signal processing apparatus according to the infrared remote control receiver having a microcomputer, the user performs the operation of the desired device, wherein the semiconductor signal processing apparatus is configured by using only the CMOS process, It shall be.; Infrared remote control receiver according to the invention is designed with a semiconductor signal processing apparatus using only the CMOS process and is excellent in noise characteristics. The semiconductor signal processing apparatus of the infrared remote control receiver according to the present invention can be performed safely amplifying function even if the external input signal is outside the input range of the input, when implemented as an integrated circuit, it is possible to reduce the area occupied on the chip. In addition, the signal envelope detection circuit of an infrared remote control receiver according to the present invention has a high detection efficiency, and also possible to securely generate an output pulse signal when the low input signal to be input.
