A unified method for nonlinear noise analysis of all-pole RF MEMS tunable filters

Summary form only given, as follows. A simple, unified approach is presented to theoretically calculate the effect of nonlinear noise in all-pole RF MEMS tunable filters. The proposed admittance-based calculation in the bandpass domain allows easy estimation of filter phase noise while considering the effect of nonlinearity, finite resonator quality factor, and frequency-dependence of inverter networks in Butterworth and Chebyshev tunable filters. Phase noise calculations are in excellent agreement with previously published work.
