CIRCUIT AND APPARATUS FOR CONNECTING A MEMS MICROPHONE WITH A SINGLE LINE

摘要

A circuit electrically connects a MEMS microphone with a single line transmitting both a DC power signal and an AC information signal. The MEMS microphone has a power interface for receiving the power signal, and an information interface for delivering the information signal. In such embodiments, the circuit includes a pair of lines that separate the power and information signals. To that end, the circuit has an information line configured to connect with the information interface of the MEMS microphone, and a power line configured to connect with the power interface of the MEMS microphone.
