Abstract
In this paper, a pW-power relaxation oscillator for
sensor node applications is presented. The proposed oscillator
operates over a wide supply voltage range from nominal down
to deep sub-threshold and requires only a sub-pF capacitor
for Hz-range output frequency. A true pW-power operation is
enabled thanks to the adoption of an architecture leveraging
transistor operation in super-cutoff, the elimination of voltage
regulation, and current reference. Indeed, the oscillator can be
powered directl
