Research Activities

Professor Gu’s group is conducting research of high efficiency and low power interconnect, ultra-low phase noise signal generation, mm-wave and terahertz integrated circuits and systems for communication, radar and imaging. Recently, her group has developed several key circuit components and state-of-the-art mm-wave subsystems. Recent development results include: a CMOS 100 GHz power amplifier with the saturated output power of Psat about 15 dBm and Power Added Efficiency (PAE) about 10%; a CMOS 100 GHz Low Noise Amplifier (LNA) with the noise figure (NF) of < 8 dB; a CMOS frequency divider up to 208 GHz with wide locking range (>37 GHz); a THz CMOS generator; a CMOS E-band synthesizer with fully programmable division ratio, wide locking range (70-78GHz) and low phase noise (-83dBc/Hz @1MHz offset); high temporal resolution (< 2K NETD) passive imagers in both W-band (75-110 GHz) and D-band (110-170 GHz) frequency ranges; ultra-low power active imager receivers for imaging and radar applications, etc.
