US 2016/0238647 A1 · SYSTEM REFERENCE WITH COMPENSATION OF ELECTRICAL AND MECHANICAL STRESS AND LIFE-TIME DRIFT EFFECTS

Abstract

Stress compensated systems and methods of compensating for electrical and mechanical stress are discussed. One example system can include a first circuit and a global stress compensation component. The first circuit can be configured to generate a first signal and can comprise at least one local stress compensation component (e.g., employing dynamic element matching, chopping, etc.). The global stress compensation component can comprise one or more stress sensors configured to sense one or more stress components associated with the system. The global stress compensation component can be configured to receive the first signal and to compensate for stress effects on the first signal.

Claims20

Dependent claims

A system, comprising:

a reference circuit configured to generate at least one reference signal, wherein the reference circuit comprises a first set of local stress compensation components that are configured to compensate for stress effects on the at least one reference signal, wherein the at least one reference signal comprises at least one of a reference voltage, a reference current, or a reference clock frequency;
and
a global stress compensation component that comprises one or more stress sensors configured to sense one or more stress components associated with the system, wherein the global stress compensation component is configured to compensate for the stress effects on the at least one reference signal based at least in part on the sensed one or more stress components.

Dependencies are inferred from the claim text.
