Brief Description
Increasingly, complex analog and RF circuits require in-situ calibration in order to function correctly in the presence of manufacturing and temporal variations. Digital correction is used to "correct" the operation of the transistor level analog circuit. Currently, the implementation structures for self-calibration are ad-hoc, with each sub-circuit often having a unique hand-crafted approach. In this project, we are determining new general algorithmic approaches to support the implementation of self-calibrating circuits. These techniques are intended to be widely employable, and have low implementation overhead. In addition, we are working on general approaches to designing the calibration sub-circuits that will improve their efficiency and implementation cost.
