Classification: CPC B  H | IPC B

Claim 16:
17. A triple-membrane MEMS device comprising:
a first membrane, a second membrane and a third membrane spaced apart from one another, wherein the second membrane is between the first membrane and the third membrane;
a sealed low pressure chamber between the first membrane and the third membrane;
a first stator and a second stator in the sealed low pressure chamber; and
a signal processing circuit configured to read-out output signals of the triple-membrane MEMS device, wherein the signal processing circuit comprises:
a negative voltage source configured to bias the first stator,
a positive voltage source configured to bias the second stator
a predetermined voltage potential configured to be coupled to the first membrane and the third membrane, and
an amplifier connected to the second membrane and configured to read-out an output signal of the triple-membrane MEMS device.
