PROBLEM TO BE SOLVED: To obtain a matched filter circuit whose power consumption is further suppressed more than that of a conventional circuit. SOLUTION: Power supply to undesired circuits is interrupted based on the rule of experience that only part of signals is to be sampled after synchronization acquisition. Furthermore, taking notice of a spread code to be 1-bit data string, an input signal is sampled and held as a time series analog signal and the result is distributed into '1' or '-1' series by multiplexers MUX1-MUX3 and the series signals are added in parallel by a capacitive coupler CP1 to supply power to the circuit intermittently. |
