Abstract

PURPOSE:To improve the rise by installing the circuit which charges the decoupling capacitor. CONSTITUTION:Potential E2 at middle point M between voltage division resistances 12 and 13 is set lower than steady active voltage EC of front-step amplifier 2 and higher than action start voltage E0 each. With the make of power switch 11, the charging is given to decoupling capacitor 7 from point M of the voltage division resistances and through diode 14. The circuit can secure the operating state quickly since the time constant is shorter than the charging given through decoupling resistance 8. At the same time, no reverse current flows at the normal state due to diode 14 thus to secure the steady state.
