Abstract
A non-linear capacitor includes a capacitor, a first and a second amplifier devices, and an input and output node for providing a charging current and a discharging current. The capacitor connects to the input and output node through the first and the second amplifier devices. When the capacitor is charging, one of the first and the second amplifier devices is conducted to vary the charging current, and the capacitor is charged by the varied charging current. When the capacitor is discharging, the other of the first and the second amplifier devices is conducted to vary the discharging current, and the capacitor is discharged by the varied discharging current. A variation trend of the charging current is opposite to a variation trend of the discharging current.
