Description
Summary:·/3· booster eligible for bothsingle-phase pumping and dual-phase pumping is developed. A closed-loop sensing scheme with analog/digital mixed-mode voltage reg-ulation helps to ensure a low ripple output voltage and high power transfer eciency. A test vehicle was implemented for a DC inputrange of 2.23.6 V and the DC output of 5 V with a load condition of 20 mA in a standard 0.35-l m 2poly-4metal CMOS process. The· dual phase mode.
