Abstract

This thesis is an analytical study of SIMOs that aims at deriving a full dynamic model of generic N-output SIMOs while referencing a SIMO buck converter as an example. Because area is a major cost metric in portables, the thesis also describes a systematic approach of optimization subject to an area constraint. A circuit-level SIMO core is explored, optimized using MATLAB, and the results are cross-checked against analytical efficiency predictions. The thesis consists of five chapters, and an appendix, and includes a list of contents, a list of tables, a list of figures, and a list of references.
Chapter 1 gives a brief introduction of the motivation, objectives, major contributions, and organization of the thesis.
Chapter 2 delves into the mathematical elements of analysis of switching regulators. A general time-variant model for SIMOs is then derived and used to derive the DC-DC characteristics of SIMOs. Analysis of loss components in a SIMO system are introduced and a general optimization procedure is described.
Chapter 3 investigates some of the recent SIMO developments in the literature and previews the various approaches of control in light of the analytical development in Chapter 2.
Chapter 4 shows an example implementation of a SIMO buck converter and cross-compares efficiency results from the optimizer with that from circuit-level simulations.
Chapter 5 presents the conclusions for this work and the suggested future work.
