Abstract

A microphone system has a package forming an interior chamber, and a MEMS microphone secured within the interior chamber. The package forms an aperture for permitting acoustic access to the interior of the chamber and thus, the MEMS microphone. The system also has two dies; namely, the system has a primary circuit die within the interior chamber, and an integrated passive device die electrically connected with the primary circuit die. The primary circuit die is electrically connected with the MEMS microphone and has at least one active circuit element.
