Classification: CPC B  H | IPC B

Claim 15:
16. 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, the signal processing circuit comprising:
a voltage source configured to bias the first stator and the second stator,
a predetermined voltage potential configured to be coupled to the first membrane and the second membrane, and
an amplifier connected to the third membrane and configured to read-out an output signal of the triple-membrane MEMS device.
