Abstract
An apparatus includes a temperature sensor, a voltage regulator, and a field programmable gate array (FPGA). The temperature sensor and the voltage regulator are adapted, respectively, to provide a temperature signal, and to provide at least one output voltage. The FPGA includes at least one circuit adapted to receive the at least one output voltage of the voltage regulator, and a set of monitor circuits adapted to provide indications of process and temperature for the at least one circuit. The FPGA further includes a controller adapted to derive a body-bias signal and a voltage-level signal from the temperature signal, from the indications of process and temperature for the at least one circuit, and from the at least one output voltage of the voltage regulator. The controller is further adapted to provide the body-bias signal to at least one transistor in the at least one circuit, and to provide the voltage-level signal to the voltage regulator.
