Abstract
An autonomous power generator unit including two
micropower sources and their management IC has been fabri-
cated: a RF power receiver and a 1 V miniature thermogenerator
combined with a micropower DC/DC up-converter are combined
with a 78% efficiency manager and charger, and a 5 nW discharge
monitor to manage and store the harvested energy in a 30 mm
/50
above-IC deposited microbattery.
