Abstract :
This paper presents a low-voltage zero quiescent current PFM boost converter which is designed with a standard TSMC 3.3/5V 0.35-μm CMOS technology. The proposed circuit can correctly operated at 0.9V supply voltage so that it can boost 0.9V supply to 3.6V by using a ringing oscillator, a multiplexer, a precise voltage detector and a proposed feedback scheme. Moreover, the proposed PFM boost converter circuit consumes zero quiescent current.
