Abstract
This paper presents a monolithic buck converter using a fully-integrated current-mode Type-III compensator for envelope tracking (ET) power amplifiers (PAs) in narrowband IoT (NB-IoT) applications. A dual-path current-mode compensator that combines a gain-boosting path and a phaseboosting path is proposed to reduce the area of the compensation network. The effectiveness of the proposed design is verified by extensive simulation results. With the proposed compensator, this design achieves 400 kHz crossover frequency at 2MHz switching frequency ($f_{SW}$).
