Professor KI Wing-Hung
Department of Electronic & Computer Engineering
The Hong Kong University of Science and Technology
Ki received his BSc degree (1984) from the University of California, San Diego, the MSc degree (1985) from the California Institute of Technology, Pasadena, and the PhD degree (1995) from the University of California, Los Angeles, all in electrical engineering.
He worked for Micro Linear Corporation, San Jose, from 1992 to 1995, on the design of power converter controllers, and joined the Hong Kong University of Science and Technology in 1995. He is now an associate professor with the Department of Electronic and Computer Engineering.
His research interests are integrated circuit techniques for power management circuits such as switching converters, bandgap references, charge pumps, low dropout regulators, power transponders for RFID and energy harvesting applications, and fundamental research in circuit analysis and design.

| Synopsis: |
The short course will cover power management circuits such as switching converters, bandgap references, charge pumps and low dropout regulators. For switching converters, the topics are converter fundamentals; CCM, DCM and PCCM operation; voltage, current and V2 control; single-inductor multi-input multi-output converters; IC design techniques of (1) control loop circuits such as clock and ramp generator, error amplifier and compensation, on-chip current sensors and slope compensation; (2) power stage design and active diodes; and (3) peripheral circuits such as UVLO and OVP. For bandgap references, the topics are op-amp based and current-voltage-mirror based bandgap references, CMOS bandgap references with and without output buffers, trimming and resistor string design. For charge pumps, the topics are charge pump topologies, gate drive, reversion reduction, charge pumps with variable conversion ratio, and multi-phase charge pumps. Finally, design issues of low dropout regulators will be highlighted. |
