Abstract
A system may include an integrated circuit comprising an on-chip power supply and an internal power rail, a gate-controlled supply switch configured to be coupled between the on-chip power supply and an external power supply such that the internal power rail is regulated by the on-chip power supply when the gate-controlled supply switch is open and the internal power rail is regulated by the external power supply when the gate-controlled supply switch is closed, and a control circuit configured to monitor conditions associated with the on-chip power supply when the gate-controlled supply switch is transitioning between switch states and based on the conditions, control a rate of charging or discharging of a capacitance coupled to a gate of the gate-controlled supply switch.
