20120308052 | Microphone Assembly - Described herein is a microphone assembly for an electronic device incorporating a microphone. The microphone assembly includes a microphone interface that enables direct coupling of inputs from the microphone to a preamplifier. For the purpose, the microphone interface includes a DC servo loop. The DC servo loop provides a DC path for supplying a DC bias current to the microphone and an AC path to receive the AC output obtained from the microphone. The AC path and the DC path allow separation of the AC output of the microphone from the DC bias current. The microphone interface is implemented using reduced number of IC pin interfaces and external components to achieve compactness of the device. | 12-06-2012 |
