Abstract

As technology progresses, semiconductor devices become smaller while operating frequencies become faster. This work presents a fast-switching low dropout regulator (LDO). Previous studies on LDO aimed to improve the power supply rejection performance at high frequencies by connecting a large capacitor off-chip at the output. More recent studies implemented on-chip capacitors; however, this still occupies a large chip area. In this work, chip area is reduced by using NMOSCAP instead of MIM capacitors. The chip is implemented using the a 0.18 μm process. The core area is 215 μm × 165 μm. The input voltage is 2V and the output voltage is 1.8V. The settling time is less than 20ns when the load current switches between 1mA and 50mA.
