Abstract
In some embodiments, a chip is provided that comprises a group of transistors and a body bias generator. The group of transistors is coupled to the body bias generator. The body bias generator is configured to body bias the transistors at a level based on one or more measured parameters associated with the chip and on an operating mode. Other embodiments are disclosed herein and/or are otherwise claimed.
Claims25
A chip, comprising:
- (a) a group of transistors;
- and
- (b) a body bias generator coupled to the group of transistors, said generator to body bias the transistors at a level based on one or more measured parameters associated with the chip and on an operating mode.
A device comprising:
- (a) a group of transistors;
- and
- (b) a body bias generator coupled to the transistors , the body bias generator to body bias the transistors to lower their voltage threshold levels during one or more active modes and to raise their voltage threshold levels during one or more less active modes.
A method, comprising:
- (a) at least indirectly measuring a threshold level associated with a transistor group in a fabricated chip;
- and
- (b) programming a body bias circuit that is part of the chip to body bias the transistors (i) to have increased frequency response in view of the measured threshold level during a most active mode, and (ii) to have reduced current leakage during a least active mode.
A system, comprising:
- (a) a microprocessor having:
- (i) a group of transistors each having a body, and
- (ii) a body bias generator coupled to the transistor bodies, said generator being configured to bias the bodies at a level based on one or more measured parameters associated with the chip and on an operating mode;
- and
- (b) a wireless interface component communicatively linked to the microprocessor.
