System and method for all electrical noise testing of mems microphones in production |
abstract |
Systems and methods for electrical testing of noise in a multi-membrane micro-electro-mechanical systems (MEMS) microphone are disclosed. The MEMS system has a test mode that includes placing the microphones' MEMS biasing networks into a reset mode, adjusting the first bias voltage for the first MEMS sensor such that a polarity matches the polarity of the bias voltage of the second MEMS sensor. The MEMS biasing networks are then placed into a sense mode, and a total noise value is obtained for the MEMS microphone system by measurement of the output of the system's preamplifier. |
