Phase Noise Analysis of MEMS-Based Phase Shifters
Phase Noise Analysis of MEMS-Based Phase Shifters Gabriel M. Rebeiz Abstract-- The effect of Brownian noise on Micro-Electro-Mechanical (MEMS)-based circuits has been calculated for MEMS-based circuits (phase shifters, delay circuits). The calculations are done for capacitive shunt MEMS switches and metal-to-metal contact series MEMS switches. The phase noise due to Brownian motion is negligible f
