Abstract:
1. A circuit comprising: a charge provider circuit operable to receive a control signal and operable to provide a charge to a body-bias voltage source of an integrated circuit responsive to said control signal; an output monitoring circuit operable to determine, independently of said control signal, whether a voltage at an output node of said charge provider circuit is an over-voltage or an under-voltage that is outside of an acceptable threshold value, wherein said output monitoring circuit is operable, independently of an external signal, to outputs said control signal which is operable to adjust said output node responsive to said determination; and a shunt circuit operable to provide a discharge path responsive to said control signal based on whether said voltage at said output node exceeds said acceptable threshold value, wherein said control signal causes said charge provider circuit to provide said charge to said body-bias voltage source based on whether said voltage at said output node is outside of said acceptable threshold value.
