Abstract
This paper presents a high voltage and low power in-
ductive DC-DC buck converter for interfacing electrostatic energy
harvesters. The system, implemented in TSMC 0.25 µm BCD,
can convert input voltages from 5 to 60 V to recharge the energy
storage system connected to the output. The system includes also
a Maximum Power Point Tracking algorithm for matching the
equivalent source resistance of harvester and AC-DC converter.
Due to power consumption constrains, a conventional implemen-
