Switched-mode DC–DC converters are roughly divided into two categories: the inductive type and the capacitive type. The first using both an inductor and a capacitor to convert the input voltage into a regulated output voltage, the latter using nothing but capacitors to achieve this. In theory inductive-type DC–DC converters provide a lossless DC–DC conversion for a continuous input-output voltage range. Capacitive DC–DC converters fail to meet this expectation. And therefore inductive-type of DC–DC converters are the dominant type of DC–DC conversion apparatus in both commercial and industrial prototypes. For a long time inductive-type DC–DC converters were thought to maintain their superiority even for monolithically integrated prototypes. But in an integrated case the inductive converters are cut short by the poor quality of the integrated inductors, the keycomponents in the design. Therefore the intuitive preference for inductive converters does not hold anymore. Moreover, integrated capacitors—crucial for the operation of the capacitive converters—are native devices in CMOS technology and can be constructed at high quality. Therefore, despite their obvious limitations, capacitive DC–DC converters are viable alternatives for the inductive counterparts. But the adoption of monolithic capacitive DC–DC converters requires an extensive analysis of the conversion characteristics. This book describes the background required for designing a fully integrated DC–DC converter in CMOS and provides a detailed discussion of a number of CMOS prototypes.
