Book 2013innovative way is the presented adaptive voltage scaling scheme, which tunes the supply voltage according to the present process, voltage and temperature variations as well as aging. The voltage is adapted “on the fly” by means of in-situ delay monitors to exploit unused timing margin, produced by s

Evaluation of the Pre-Error AVS Approach,iations on the voltage control can be analyzed very accurately and efficiently. In the following we will also cover the power overhead introduced by the necessary AVS circuitry consisting of the Pre-Error flip-flops and the AVS control unit. As a proof of concept, the application of Pre-Error AVS to an image processing circuit is finally shown.

Conclusion,increasing PVT variations as well as aging effects in integrated circuits. This Pre-Error AVS approach reduces unnecessary voltage safety margin by adapting the supply voltage to the actual operating condition of a chip and thereby optimizes power consumption.
