Abstract

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.
