Abstract
In recent years, there has been a push towards
high-density and monolithic DC-DC converters to support appli-
cations such as performance and mobile computing, consumer
electronics, and renewable energy. Switched capacitor (SC)
converters have started to gai n traction for a number of these
applications, but are still subject to fundamental limitations
that drive them towards expens ive process options and high
switching frequencies. Variable regulation is challenging with the
SC approach, and c
