Abstract
A field programmable gate array (FPGA) includes a set of monitor circuits adapted to provide indications of process, voltage, and temperature for at least one circuit in the FPGA, and a controller adapted to derive a range of body-bias values for the at least one circuit from the indications of process, voltage, and temperature for the at least one circuit. The FPGA further includes a body-bias generator adapted to provide a body-bias signal to at least one transistor in the at least one circuit. The body-bias signal has a value within the range of body-bias values.
