Abstract
PURPOSE:To improve the precision of a divider with its constitution simplified without adding a special divider circuit to the divider which uses an automatic gain control circuit, by switching the automatic gain control circuit by an analog switch. CONSTITUTION:This divider is equipped with the automatic gain control circuit composed of operation amplifiers OP1, OP2 and OP3 whose gains are controlled automatically, analog switches S1 to Sn which divide an input signal applied to input point VIN of the circuit into a divisor signal and a dividend signal, analog switch S0 which conducts the feedback circuit of the circuit in a divisor input state and cuts off it in a dividend input state connecting to the output of amplifier OP1, and a FET. Further, capacitor C1 which holds the gain after the divisor signal input until a dividend signal is inputted is provided to the feedback circuit of amplifier OP1. Then, the output side of amplifier OP2 is connected to output point VOUT from which a division value is outputted, thereby constituting the divider.
