Abstract
In this article, a fully integrated capacitorless low-
dropout regulator (LDO) is presented for Internet-of-Things
(IoT) edge sensor application. To achieve sub-1-V operation and
fast transient response with low quiescent current, the con-
ventional operational transconductance amplifier (OTA)-based
error amplifier (EA) is replaced with oscillator-based voltage-
to-time converter and time-domain signal processing, includ-
ing time-domain edge-based frequency comparator (FC) and
event-driven voltag
