Abstract
Presented are structural and circuit techniques for DCDC converters with consumption below power switch leakage and having efficiency above 80% at load currents from few μA to 100 s of mA. These techniques have been used in industrial ICs of energy harvesting systems, in the wireless sensor network power management, and in IoT electronics. Considered are process selection, transistor sizing for nA currents, biasing, voltage references, active rectifiers, comparators, oscillators, error amplifiers, and inductor current measurement, followed by selection of the DCDC operation mode and IC design examples.
