Novel high-Q bondwire inductor for MMIC

A novel high-Q on-chip inductor using bondwire loops is proposed for low cost and high performance GaAs MMIC. The measured maximum quality factor and the self-resonant frequency are 21.1 (26.5) and 11.3 (17.0) GHz for 3.5 (2.1) nH inductance, respectively. The electrical variations are measured within 5% tolerance. The on-chip bondwire inductor can be effectively used for developing GaAs MMIC with no external inductors.
