ABSTRACT:
A smoothing circuit for realizing the miniaturization and the increase of integration scale of a circuit and for easily varying attack time and release time. This smoothing circuit comprises a capacitor, voltage comparator, charging circuit, and discharging circuit. The voltage comparator compares the terminal voltage of the capacitor with its input voltage and actuates the charging circuit or the discharging circuit according to a comparison result. The charging circuit charges the capacitor by intermittently supplying charging current. The discharging circuit discharges the capacitor by allowing discharging current to flow intermittently.
