With the development of computing technology, the demand for next-generation voltage regulators (VRs) to power the modern microprocessors is rising. The next-generation VRs should be more compact and perform with faster dynamic response under increasingly large load transients. Charge balance control concept has been introduced to achieve much lower output voltage deviations and shorter settling time than linear mode controllers. However, the existing implementations of charge balance controllers are too complicated to be widely used in practical VR applications. Therefore, to improve the transient response of a VR in a practical manner, five novel ideas are presented in this thesis.
