    摘要: A sensor arrangement comprises a first capacitive sensor with a first and a second terminal, a second capacitive sensor with a first and a second terminal, a charge pump arrangement coupled to the first terminal of the first capacitive sensor and to the first terminal of the second capacitive sensor, and a differential output. The differential output comprises a first terminal coupled to the second terminal of the first capacitive sensor and a second terminal coupled to the second terminal of the second capacitive sensor. The first and the second capacitive sensor having opposite geometric orientation.
