ABSTRACT:
Structure and process for compensating threshold voltage variation due to process variation. The structure includes a circuit segmented into sub-blocks having a predetermined size corresponding to a characteristic length associated with a process variation. A local circuit is located in each circuit sub-block, and a reference signal coupled to each local circuit. The local circuit generates a compensation signal in response to the reference signal to adjust an electrical parameter of the respective sub-block to a predetermined value.
