Efficient Switch capacitor DC to DC supply voltage up-converter

תיאור הפרויקט ותכולתו:

Often integrated circuits require voltage above the supply rail, VCC.  In this project, you will design a switched capacitor DC-to-DC up-converter which will raise the supply voltage to roughly 1.4X VCC.  This circuit must supply under a variety of loading conditions from 10’s of uA to several mA and a large VCC range.  This must also be done at high power efficiency (> 80%).  It is expected that this will be a closed loop system using pulsed frequency modulation.  This circuit will be used in security applications.
