Abstract

Radiation sensors detect and convert radiation of interest (e.g. charged particles, neutrons, X- and gamma-rays) into electric charge. Reading out from radiation sensors requires highly specialized electronics. In this talk, the low-noise design techniques and circuits adopted in state-of-the-art CMOS ICs for radiation detectors are presented. Examples in space, physics, and medical applications are given, explaining some special issues on CMOS devices including lifetime and radiation-induced leakage.

Speaker Biography

Dr. Shaorui Li received the PhD degree in 2005 in electrical engineering from Columbia University. She joined Agere Systems (formerly Bell Labs Microelectronics) in 2005 designing RF and mixed-signal ICs for 3G/LTE wireless transceivers. Since 2009, she joined Brookhaven National Laboratory developing low-noise CMOS ICs for radiation detectors. She holds three patents and has authored over 20 technical papers including one book chapter. Her main interests are in the area of analog and mixed-signal integrated circuits.
