Abstract:
     The infrared automatic control circuit whose static watt consumption is less than 0.6 milliwatt is characterized by that in its circuit a CMOS integrated circuit chip (IC) is placed; it has no need of magnification and shaping; a narrow pulse train is preset on the monostable trigger end so as to make the static monostable be in critical state to be triggered, and when a weak useful signal which is identical to the preset pulse in wave form and phase is superposed, the threshold value can be broken through so as to make trigger turn over. The base-emitter voltages of IC peripheral transistors are less than 0.1V both in static and in dynamic state. Said circuit is simple in structure, reliable, and low in power consumption.
