Abstract
In an integrated circuit having an on-chip power supply, a voltage maintenance circuit includes a decoupling capacitor connected between the output node and ground, a supplementary capacitor connected between a supplementary node and ground and a controllable transistor connected between the two capacitor nodes, so that when the output voltage drops below a threshold a reference circuit turns on the controllable transistor, thereby supplying extra charge to the output node and restoring it to its design voltage more quickly than the power supply could.
