Abstract

This thesis presents a study and the design of a high-speed switched capacitor boost converter with small capacitors to be integrated into SOCs. For boost converters, you can use either switched inductor-based regulators or switched capacitor regulators. Switched inductors need access to off-chip inductors which increases costs and puts limitations on the system. With the switched capacitor, you can use no external components and integrate the converter anywhere on the chip. We propose a new system that enables switched capacitor boost converters to achieve very fast transient response up to 6 mA/100 ps by utilizing a pseudo-ADC at the output of the converter. The ADC changes the code depending on the load which is used to optimize the number of switches needed. The design can also be extended using extra tiles of the unit converter to support higher current (24mA) with the same performance. The thesis is divided as follows,
Chapter 1
Chapter 1 gives a short introduction, the motivation behind this work, contributions, and how this thesis is organized.
Chapter 2
Chapter 2 delves deeper into the basics of the regulators and focuses on switched capacitors regulators and surveys prior art. A basic analysis will be presented in this chapter with some of the design trade-offs.
Chapter 3
Chapter 3 describes the proposed system and discusses how it achieves the very fast transient response of 6 mA/100 ps. More details on the circuit design to make it practical and suitable for SOC integration. It also shows the path for extending the design to support higher currents.
Chapter 4
Chapter 4 shows the simulation results of the proposed system and compares the results to the state of the art. It also shows the results of the extended design that supports up to 24mA and achieves a very fast transient of 24 mA / 100 ps
Chapter 5:
In this chapter we present the thesis conclusion and list some suggested future work. We highlight some ideas that we did not have time to explore
