A 310-nA Quiescent Current 3-fs-FoM Fully Integrated Capacitorless Time-Domain LDO With Event-Driven Charge Pump and Feedforward Transient Enhancement.
IEEE J. Solid State Circuits（2021）
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 conventional operational transconductance amplifier (OTA)-based error amplifier (EA) is replaced with oscillator-based voltage-to-time converter and time-domain signa...
