Rugged HBT Class-C Power Amplifiers with Base-Emitter Clamping
Xi Luo, Subrata Halder, James C. M. Hwang
The ruggedness of HBT Class-C power amplifiers was improved by adding an anti-parallel diode to the amplifier input to limit the negative swing of the base-emitter voltage. The imp…
Scaling and High-Frequency Performance of AlN/GaN HEMTs
Xi Luo, Subrata Halder, Walter R. Curtice +4
Small- and large-signal RF characteristics were measured on AlN GaN HEMTs with 80-160 nm gate length and 100-300 μm width. Consistent with the literature, current-gain cut-off freq…
Intermodulation distortion of actuated MEMS capacitive switches
Xi Luo, Yaqing Ning, David Molinero +3
For the first time, intermodulation distortion of micro-electromechanical capacitive switches in the actuated state was analyzed both theoretically and experimentally. The distorti…
Scanning Microwave Microscopy of Aluminum CMOS Interconnect Lines Buried in Oxide and Water
Xin Jin, Kuanchen Xiong, Roderick Marstell +6
Using a scanning microwave microscope, we imaged in water aluminum interconnect lines buried in aluminum and silicon oxides fabricated through a state-of-the-art 0.13 um SiGe BiCMO…
