Donald Y.C. Lie, Ph.D., Keh-Shew Lu Regents Chair Professor, Dept. of Electrical and Computer Engineering, Texas Tech University.
Professor Lie will provide some research highlights from his group on the power efficient RF/Analog integrated circuits (ICs) and System-on-a-Chip (SoC) design for wireless and medical electronics applications. For example, the latest broadband wireless standards (4G/802.11n) utilize inherent spectral-efficient modulation schemes with high peak-to-average power ratios (PAPR) with wide signal bandwidth (40-80MHz), which demand high linearity RF power amplifier (PA) design techniques that can offer excellent power-added efficiency (PAE) at both the maximum peak power and lower power “back-off” levels to save power. On the medical electronics side, Professor Lie will briefly discuss his work on a novel intelligent RFID System for handwashing compliance to reduce hospital acquired infections; a noncontact wireless vital signs and motion monitoring sensor; some Implantable medical devices work such as on the ultralowpower electronics for implantable cardioverter defibrillator (ICD), cochlear implants, etc.; and the gait analysis, fall detection/prevention using wearable wireless sensor system for balance disorders testing.
