Abstract
A programmable logic device (PLD) includes mechanisms for adjusting or setting the body bias of one or more transistors. The PLD includes a body-bias generator. The body-bias generator is configured to set a body bias of one or more transistors within the programmable logic device. More specifically, the body-bias generator sets the body bias of the transistor(s) so as to trade off performance and power consumption of the transistor(s).
Claims16
1-18. (canceled)
A programmable logic device (PLD), comprising:
- a control circuitry;
- a body-bias generator coupled to the control circuitry, the body-bias generator configured to set a body bias of a transistor within the programmable logic device (PLD);
- and
- a variable impedance device coupled to the control circuitry, the variable impedance device configured to control power dissipation of a first circuit within the programmable logic device (PLD).

A programmable logic device (PLD), comprising:
- a temperature sensor, the temperature sensor configured to sense a temperature of a first circuit in the programmable logic device (PLD);
- a body-bias generator configured to set a body bias of a set of transistors in response to a control signal;
- and
- a control circuit coupled to the temperature sensor and the body-bias generator, the control circuit configured to provide the control signal in response to a signal received from the temperature sensor.
