An Analysis of Source Connections in GaN Power Transistor Packages
/forschung/publikationen/an-analysis-of-source-connections-in-gan-power-transistor-packages
This paper presents an analysis of different variations to contact the source of GaN power transistors in a package. Two variants relying on bondwires, and three variations using source vias are…
A Low Voltage 24 GHz VCO in 130nm CMOS For Localisation Purposes in Sensor Networks
/forschung/publikationen/a-low-voltage-24nbspghz-vco-in-130nm-cmos-for-localisation-purposes-in-sensor-networks
A low-voltage CMOS cross-coupled voltage controlled oscillator (VCO) in 130nm IBM-CMOS process is presented. Due to system considerations, tuning voltage is centered around 1V. The VCO delivers…
A High-Gain X-Band GaN-MMIC Power Amplifier
