Ultra-fast and high efficiency DC/DC conversion for data processing circuits. - 178 p.

Adviser: Wai Tung Ng.

Thesis (M.A.Sc.)--University of Toronto (Canada), 2003.

Powering next-generation microprocessors requires high-efficiency high-performance DC/DC converters with extremely low-voltage high-current fast-transient-response output. To address these challenges, comprehensive studies are carried out.

520 $a Powering next-generation microprocessors requires high-efficiency high-performance DC/DC converters with extremely low-voltage high-current fast-transient-response output. To address these challenges, comprehensive studies are carried out.
520 $a A zero-voltage-switching quasi-square-wave (ZVS-QSW) buck converter with fixed-frequency peak-current-mode (PCM) control was developed. Targeting at integration with deep sub-micron commercial CMOS process using a minimum number of external components, a series of innovations for power conversion technology were examined. This includes a current-conveyor-based Sense-FET scheme for current sensing, and fast "adaptive" dead time control using Delay-Locked-Loop-like Dead-Time-Locked Loops (DTLLs) for accurate soft-switching realization. These solutions collectively minimize switching losses thus maximize power converting efficiency at high switching frequencies, lower EMI noise and voltage stress on power device, while providing ultra-fast transient response and the convenience for paralleling multi-phase DC/DC converters. The design was simulated with a 3.3V input and a 1.3V 10A nominal output for conceptual demonstration purposes. The basic electrical parameters are scalable for various applications.
