Abstract:
A body-bias voltage source having an output monitor, charge pump, and shunt. a shunt circuit having on/off control is coupled to the output monitor and to the output of the charge pump. Upon sensing that the output voltage of the charge pump is above a desired value, the output monitor may disable the charge pump circuit and may enable the shunt circuit to reduce the voltage at the output of the charge pump. When the voltage output of the charge pump is below the desired value, the output monitor may disable the shunt circuit and may enable the charge pump circuit. A shunt circuit having proportional control may be substituted for the shunt circuit with on/off control.
