Abstract or Summary
  • A new coupled circuit and electrostatic/mechanical simulator (COSMO) for the design of RF MEMS VCOs is presented in this thesis. The numerical solution of device level equations is used to accurately compute the capacitance of a MEMS capacitor. This coupled with a circuit simulator facilitates the simulation of circuits incorporating MEMS capacitors. Different MEMS capacitor structures are simulated and their effect on VCO performance is studied. In addition, the noise from the MEMS capacitor is combined with a nonlinear circuit-level noise analysis to determine the phase noise of RF MEMS VCO. Simulations of two different MEMS VCO architectures show good agreement with experimentally observed behavior.
