摘要:
A bias generator unit is provided that includes a central bias generator to provide a bias voltage, a local bias generator to receive the bias voltage and a reference voltage and to provide a forward body bias signal or a reverse body bias signal. The bias generator may include a charge pump to output (or provide) a reference voltage to a reference generator, which in turn provides reference signals to the central bias generator. As a result, the local bias generator may control the body bias signal provided by the local bias generator.

A system may include acquisition of a supply voltage information representing past supply voltages supplied to an electrical component, acquisition of a temperature information representing past temperatures of the electrical component, and control of a performance characteristic of the electrical component based on the supply voltage information and the temperature information. Some embodiments may further include determination of a reliability margin based on the supply voltage information, the temperature information, and on a reliability specification of the electrical component, and change of the performance characteristic based on the reliability margin.

A bias generator is provided that includes a central bias generator to provide a first bias voltage and a local bias generator to receive the first bias voltage and to provide a second bias voltage. The central bias generator may include a replica bias generator circuit substantially corresponding to the local bias generator.
摘要:
A controller for providing within-die body bias includes a signal generator for generating different bias signals and a selector to route the bias signals to one or more specific types of transistors within the sections of the die. The controller may further include a plurality of secondary body bias generators, each disposed in a respective one of the die sections for translating the signals from the generator into local bias values. Through this controller, adaptive body bias techniques may be implemented which improve the bin split and overall performance of fabricated processors or other types of circuits formed on the die.
摘要:
A local bias generator generates forward body bias that tracks variations in a supply voltage of a functional block containing one or more circuits having field-effect transistors. The bias is generated using a single-stage source-follower formed from a pair of matched transistors. In operation, the transistors convert a first bias signal into a second bias signal based on a difference between the supply voltage and a reference voltage. The first bias signal and reference voltage may be generated by a central bias generator.
