Abstract:

The front-end electronics design for a MEMS microphone array is presented for aero-acoustic applications. It is compliant with the requirements of wind tunnel tests: 100 Hz – 100 kHz bandwidth, 140 dB dynamic range. A multiplexing approach is adopted to reduce the signals distribution of an 80 elements array with two-sections microphones. Considerations for a digital output sensing system are included
