摘要： A characteristic is measured on multiple portions of an integrated circuit, and the supply voltage adjusted based on the measurements. In an embodiment, the characteristic corresponds to propagation delay which indicates whether the integrated circuit is implemented with a strong, weak or nominal process corner. In general, the supply voltage can be increased in the case of a weak process corner and decreased in the case of a strong process corner.

摘要： A switching regulator provided according to an aspect of the present invention contains uses one or more error samples from prior iterations, in addition to an error sample of the present iteration, to determine the correction for the present iteration. Due to the use of multiple samples, a switching regulator may provide a regulated signal which is at least substantially constant even in the presence of line/load variations. A controller determining the correction can be implemented either in analog or digital domain.
