Smoothing circuit
First Claim
1. A smoothing circuit comprising:
- a capacitor;
a voltage comparator which compares a terminal voltage of said capacitor and an input voltage;
a charging circuit which intermittently charges said capacitor when said input voltage is higher relatively than said terminal voltage; and
a discharging circuit which intermittently releases a discharging current from said capacitor when said terminal voltage is lower relatively than said input voltage.

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.
