Power Management Techniques for Integrated Circuit Design

Ke-Horng Chen, Full-Professor, Electrical Engineering Department, National Chiao Tung University, Hsinchu, Taiwan; Associate Editor, IEEE Transactions on Power Electronics, and IEEE Transactions on Circuits and Systems II.Ke-Horng Chen received his Ph.D. in electrical engineering from National Taiwan University, Taipei, Taiwan, in 2003. From 1996 to 1998, he was a part-time IC Designer at Philips, Taipei, Taiwan. From 1998 to 2000, he was an Application Engineer at Avanti, Ltd., Taiwan. From 2000 to 2003, he was a Project Manager at ACARD, Ltd., where he was engaged in designing power management ICs. He is the author or coauthor of more than 100 papers published in journals and conferences, and also holds several patents. His current research interests include power management ICs, mixed-signal circuit designs, display algorithm and driver designs of liquid crystal display (LCD) TV, red, green, and blue (RGB) color sequential backlight designs.
