Abstract
A stabilized power supply realized by chip-integrated
micro fuel cells within an extended CMOS process is presented in
this paper. The fuel cell system delivers a maximum power output
of 450 μW/cm
/50. The electronic control circuitry consists of an
LDO, an on-chip oscillator and a programmable timing network.
The core system consumes an average power of 620 nW. The
system reaches a current efficiency of up to 92% and provides a
constant output voltage of 3.3 V.
