Abstract
An integrated circuit device can include at least a first bi-directional biasing circuit having a first substrate portion containing a plurality of first transistors; a first control digital-to-analog converter (DAC) to generate any of a plurality of first target values in response to a first target code; a first detect circuit configured to generate a difference value between the first target values and a first limit value; and at least a first charge pump circuit configured to drive the first substrate portion between a forward body bias voltage and a reverse body bias voltage for the first transistors in response to first target values. Embodiments can also include a performance monitor section configured to determine a difference between the voltage of the first substrate portion and a target voltage. Control logic can generate first code values in response to the difference between the voltage of the first substrate portion and the target voltage. Methods are also disclosed.
