How Smart Does a MEMS Microphone Need to Be?
ABSTRACT
In the past years, the industry has managed a huge increase in the MEMS microphone performance to a point where it starts to rival studio microphone quality. At the same time, current consumption has been reduced with each new generation paving the way towards new audio use-cases such as noise cancelling earbuds (TWS) and audio-enabled wrist bands. This trend will continue and require new strategies to feed the hunger towards always higher performance at lower power. Intelligent performance management emerges as a viable path to continue the trend. In a new world of “context awareness,” system components will only be given the minimum amount of power needed to perform a given task. The question is: which performance level is needed and when? Who manages and who gets managed. Or in other words: “How smart does a MEMS microphone need to be?”
