Abstract:
The present invention provides a tunable voltage controller for use with a sub-circuit. In one embodiment, the tunable voltage controller includes a diode-connected MOS transistor contained in a doped well of a substrate and configured to provide a voltage for the sub-circuit. Additionally, the tunable voltage controller also includes a biasing unit configured to adjust the voltage by selectively connecting the doped well to one of a plurality of voltage sources or to a variable voltage source.
