Abstract
A digital microphone, the microphone includes a microelectromechanical (MEMS) component and a frequency boost component. The MEMS component is configured to convert. sound into an electrical signal. The frequency boost component is configured to receive the electrical signal and ultrasonically boost the electrical signal to create a frequency response. The frequency response does not substantially affect an audio band of interest of the microphone.
