摘要:
Various embodiments provide for an integrated temperature sensor and microphone package where the temperature sensor is located in, over, or near an acoustic port associated with the microphone. This placement of the temperature sensor near the acoustic port enables the temperature sensor to more accurately determine the ambient air temperature and reduces heat island interference cause by heat associated with the integrated circuit. In an embodiment, the temperature sensor can be a thermocouple formed over a substrate, with the temperature sensing portion of the thermocouple formed over the acoustic port. In another embodiment, the temperature sensor can be formed on an application specific integrated circuit that extends into or over the acoustic port. In another embodiment, a thermally conductive channel in a substrate can be placed near the acoustic port to enable the temperature sensor to determine the ambient temperature via the channel.
