ABSTRACT:
Power switches of circuits at respective stages of a low noise amplifier, demodulators, low-pass filers, variable gain amplifiers, and analog-to-digital converters are controlled to be off by an operation control unit in a non-reception period of an impulse signal. An increase in power consumption due to the adoption of an active filter or a variable gain amplifier is compensated for by a reduction in power consumption through intermittent operations of the circuits at the respective stages according to on and off control of the power switches.
