Abstract
This article introduces a compact NMOS-only volt- age reference that is able to operate down to a 0.25-V supply voltage and 5.4-pW power consumption. This allows reliable generation of a stable output voltage even in harvested systems under highly uncertain environmental conditions. At the system level, pW-power, 0.25–1.8-V operation, and a competitive power supply rejection ratio (PSRR) relax or eliminate the need for intermediate power conversion and supply regulation for additional power and
