Abstract
An MEMS microphone package includes a circuit board and an MEMS microphone chip. The MEMS microphone chip, mounted on the circuit board, includes a substrate, an MEMS transducer formed on the substrate, and a readout circuit also formed on the substrate. The MEMS transducer generates a sound signal according to sound pressure variations. The readout circuit reads the sound signal from the MEMS transducer.
