    摘要： A MEMS microphone assembly includes a MEMS transducer element having a back plate and a diaphragm displaceable relative to the back plate. A bias voltage generator is adapted to provide a DC bias voltage applicable between the diaphragm and the back plate. An amplifier receives an electrical signal from the MEMS transducer element and provides an output signal. The amplifier is adapted to amplify the electrical signal from the MEMS transducer element according to an amplifier gain setting. A processor is adapted to carry out a calibration routine at power-on of the microphone assembly determining information regarding the DC bias voltage and/or the amplifier gain setting.

    摘要： An assembly includes an analog signal processing unit. An analog signal path and an amplifier an automatic gain control unit are coupled to the signal path. Further to the output of the amplified analog signal, a gain information is provided as an analog or digital signal at a gain information output. This information can be used for further processing the signal, e.g., by automatic noise compression or to control further signal processing units.

    摘要： A microphone arrangement has an SMD housing with a sound inlet opening. A transducer receives sound waves through the sound inlet opening and converts the received sound waves into electrical signals. An analog-to-digital converter provides digital signals. An interface control unit with a digital interface is used by the chip to transmit data serially to an external device. At least one further interface is connected to a peripheral device such that the at least one further interface can be used to transmit data between the peripheral devices and the interface control unit. The transducer, the analog-to-digital converter, the interface control unit and the at least one further interface are integrated in the SMD housing.
