Abstract
A CMOS switched-capacitor reference is combined
with a switched-capacitor voltage doubling charge pump to pro-
duce a compact regulated 3.2-V power supply from an input that
ranges from 1.8 to 3.5 V. It can supply up to 6 mA at minimum
input. The switched-capacitor topology uses a single PN junction
and could allow for inputs and outputs less than 1 V. The concept of
constant frequency charge pump regulation is discussed, as is the
theory behind stability, load regulation, and efficiency. Measure
