Abstract
This article presents an energy-efficient, low-noise,
and bipolar-output step-up switched-capacitor converter (SCC)
with ultralow dropout post-regulation, which aims to power
a noise-sensitive thin-film transistor (TFT) circuitry in mobile
applications. The residual-energy-recycled (RER) step-up SCC
is proposed to realize fine-grained voltage conversion ratios
(VCRs) without degrading the power efficiency. It also enables
the current density to be highly relaxed, thereby integrating many
capacitors
