Filed: 1987-03-20
Abstract: PURPOSE:To reduce the power consumption by giving a potential obtained when the circuit is made stable to a capacitor holding a DC potential of an input part in a clamp circuit having two capacitors to hold the DC potential of an input section and to detect the potential of an output section so as to eliminate the loss time till the power supply rising characteristic is made stable. CONSTITUTION:A voltage source E1 is provided as a stable means giving a potential obtained when the circuit is stabilized to a capacitor C1 and has an output potential V1 nearly equal to the potential VCP to which one terminal N3 of the capacitor C1 is charged when the circuit is stabilized and is connected between the capacitor C1 and ground. In applying power, the other terminal of the capacitor C1 is fixed to a potential nearly equal to the potential VCP immediately by the voltage source E1. Even when the current supply capability of a differential amplifier A2 is not sufficiently large, the potential at a terminal N3 rises up to the potential VCP instantly. Thus, the loss time by which the circuit is made stable does not exists and it is not required to use an amplifier A2 having a large current supply capability, then the power consumption is not increased.
