PPT-CHAPTER 4 Optimizing Capacitance and Switching Activity to Reduce Dynamic Power

SECTIONS 17 By Astha Chawla Introduction C and A are intertwined P V 2 X f x C effective ILP Frequency increase gt Power problem Factors affecting A Complexity of the processor. This gives rise to many serious problems including poor noise immunity a need for slope compensation and peaktoaverage current errors which the inherent ly low current loop gain cannot correct Average current mode control eliminates these problems a Chapter Outline. Metrics. Dynamic power. Static power. Energy-delay trade-off’s. Metrics. Delay (sec):. Performance metric. Energy (Joule). Efficiency metric: effort to perform a task. Power (Watt). Chapter 24 What is Capacitance? • Capacitance (C) is equal to the Charge (Q ) between two charges or charged “regions” divided by the Voltage (V) in those regions͘  Electromechanics. 2013. J.

At the conclusion of an activity which have been subsidized by EPS, the Student Chapter must submit a follow-up report to the EPS Director of Student Programs briefly describing the activity, the attendance and the benefits. For this purpose, please complete the forms in the next few pages and add more page as necessary. Where possible, captioned photographs should be included in your report. For those activities where funds from EPS have been used, a scanned copy of a simple financial statement endorsed by the Student Chapter Advisor should also be inserted in a page of the report for that activity. .
