摘要

Circuit (1a) including an analog circuit processes an analog input signal (Vin). Moreover, the circuit (1a) including the analog circuit outputs a coefficient s1 indicating predetermined characteristic of the analog circuit of the circuit (1a) including the analog circuit and inputs it to a coefficient detection/control circuit (1b). The coefficient detection/control circuit (1b) processes and detects the coefficient s1 as a signal value, thereby detecting the characteristic of the analog circuit. The coefficient detection/control circuit (1b) outputs a control signal s2 in accordance with the detection result of the obtained coefficient s1 and inputs it into the circuit (1a) including the analog circuit. Thus, the coefficient detection/control circuit (1b) adjusts the operation state of the analog circuit and controls the operation of the circuit (1a) including the analog circuit. Thus, it is possible to use the manufactured analog circuit with a high accuracy and realize an electronic circuit device capable of reducing the power consumption and the circuit size of the analog circuit.
