Abstract
A MEMS transducer includes a first and a second differential MEMS sensor device. The first differential MEMS sensor device includes a first and a second electrode structure for providing a first differential output signal, and a third electrode structure between the first and second electrode structure. The second differential MEMS sensor device includes a first and second electrode structure for providing a second differential output signal, and a third electrode structure between the first and second electrode structure. A biasing circuit provides the third electrode structure of the first differential MEMS sensor device with a first biasing voltage and provides the third electrode structure of the second differential MEMS sensor device with a second biasing voltage. A read-out circuitry combines the first and second differential output signal in an anti-parallel manner.
