Abstract

This work applies mu analysis and synthesis techniques to develop a robust strategy for damping resonant modes in micromachined directional microphones of the parallel capacitive type. By properly selecting a weighting function, a robust controller is successfully designed via the D-K algorithm. Linear simulations show that the resonant mode of a directional microphone can be flattened out, and pushed to a frequency beyond the sensitivity of the human ear. The closed loop responses are free of ringing effects observed in open loop even for the worst-case parameter values.
