Abstract
PURPOSE:To stabilize an output signal in a short time by adding a switch which goes to ON for a constant time only at the time of applying a power source and forming a channel to charge a holding capacity to a prescribed potential. CONSTITUTION:A switch 6 to be ON only for a prescribed time only at the time of turning ON a power source is added between a positive side input terminal 14 of a feedback amplifier 13 and a holding capacity 12. At the time of applying the power source, the accumulation charge quantity of the holding capacity 12 is zero, and for the output signal, the output to overlap a signal to a direct current potential zero is obtained. Next, since the switch 16 goes to ON at a time t=0, a potential VCL of the input terminal of the feedback amplifier 13 is charged through the ON resistance (RS) the switch 16 to the holding capacity 12, and the direct current potential of the output signal raises at a time constant of an ON resistance (RS) of the switch 16 and a holding capacity 12(CH). For example, at the time of RS=500OMEGA, 500OMEGAX5muF=2.5ms is obtained and the until the output signal is stable is widely shortened.
