Download Variation-Aware Adaptive Voltage Scaling for Digital CMOS by Martin Wirnshofer PDF

By Martin Wirnshofer

expanding functionality calls for in built-in circuits, including constrained strength budgets, strength IC designers to discover new methods of saving energy. One leading edge approach is the offered adaptive voltage scaling scheme, which tunes the provision voltage in response to the current procedure, voltage and temperature adaptations in addition to getting older. The voltage is customized “on the fly” by way of in-situ hold up displays to use unused timing margin, produced through state of the art worst-case designs. This publication discusses the layout of the improved in-situ hold up screens and the implementation of the full control-loop comprising the displays, a control-logic and an on-chip voltage regulator. An analytical Markov-based version of the control-loop is derived to investigate its robustness and balance. Variation-Aware Adaptive Voltage Scaling for electronic CMOS Circuits presents an in-depth evaluation of the proposed voltage scaling scheme while utilized to an mathematics and a picture processing circuit. This booklet is written for engineers drawn to adaptive thoughts for low-power CMOS circuits.
