Fully On-Chip High Q Inductors Based on Microtechnologies

Shah K., Khalid N., Singh J., Le H.P., Devlin J., Sauli Z., La Trobe University, AU

The fast growing demand of wireless communications for voice and data has driven recent efforts to dramatically increase the levels of integration in radio frequency (RF) transceivers. Passive components such as inductor play important role [...]

Design Optimization of Micromachined High Aspect Ratio 3D On-Chip Solenoid Inductor

Chomnawang N., Lu H., Colinjivadi K., Lee J., University of Texas at Dallas, US

We report the simulation work done by using Sonnet EMÔ on high aspect ratio (1:4 and 1:8) 3D on-chip air-core solenoid inductors. Simulations on 2, 3, and 5-turn inductors with 200 and 400 mm high [...]

Coupled Substrate-resonator-electrostatic Simulation and Validation fo High-Q MEMS Resonator Performance

Park K.C., Park Y.H., Park K.C., Park Y.H., University of Colorado at Boulder, US

Vibration energy transmission from MEMS resonator through anchor to substrate, viz., anchor loss, is examined by utilizing the coupled substrate-resonator-electrostatic numerical model. The resonator is electrostatically excited beam-type structure anchored at both ends onto multi-layered [...]
