摘要

基于时间的PID补偿器结合了模拟控制器和数字控制器的优点，实现了高频低静态电流降压变换器。该降压变换器采用180nm CMOS工艺制造，工作频率范围宽(10-25MHz)，峰值效率高于94%，静态电流仅为2μA/MHz。

A 10–25MHz, 600mA buck converter using time-based PID compensator with 2µA/MHz quiescent current, 94% peak efficiency, and 1MHz BW

A time-based PID compensator that combines the advantages of both analog and digital controllers is used to implement a high frequency low quiescent current buck converter. Fabricated in 180nm CMOS process, the proposed buck converter operates over a wide range of switching frequencies (10-25MHz) and achieves better than 94% peak efficiency while consuming a quiescent current of only 2μA/MHz.
