Abstract

A body bias control circuit including an output coupled to provide a bias voltage to a body terminal. The body bias control circuit is configured to change the bias voltage from a first bias voltage to a second bias voltage over a period of time in which a magnitude of an effective rate of change of the bias voltage varies over the period of time. For voltages between the first and second bias voltages closer to a source voltage, the magnitude of the effective rate of change is smaller than for bias voltages between the first and second bias voltages further from the source voltage.
