A VARIABLE-ADAPTIVE INTEGRATED COMPUTATIONAL DIGITAL LOW DROPOUT REGULATOR

Abstract:

A Computational Digital Low Dropout (CDLDO) regulator is described that computes a required solution for regulating an output supply as opposed to traditional feedback controllers. The CDLDO regulator is Moore's Law friendly in that it can scale with technology nodes. For example, CDLDO regulator of some embodiments uses a digital approach to voltage regulation, which is orders of magnitude faster than traditional digital LDOs and enables regulation at GHz speeds, making fast dynamic DVFS a reality. The CDLDO also autonomously tunes out the effects of process-voltage-temperature (PVT) and other non-idealities making the settling time totally variation tolerant.
