Short Course: Integrated DC-DC Converters for Low-Power Applications: From Discrete Towards Fully-Integrated-CMOS Power Management Tutorial

In this session, trends and techniques towards fully integrated CMOS DC-DC converters for low-power applications are studied. Both inductive and capacitive DC-DC converters are analyzed towards the objective of full integration with external components. The required onchip components, such as inductors, capacitors and switches, are discussed. Different control-loop techniques are presented in order to achieve high integration density and meet low ripple requirements. Many recent design techniques, such as multi-core, gearbox and SPCR (Scalable Parasitic Charge Redistribution) are studied. Different design styles, both boost and buck, are analyzed and compared with classical LDO regulators.
