  • Patent number: 8164352
    Abstract: A capacitance detecting apparatus which can detect the change in minute capacitance of a measuring object with high sensitivity comprises a signal generator, a differential amplifying circuit, and a detecting unit. The signal generator generates a probe signal w(t) to be applied to one end of the measuring object. The differential amplifying circuit amplifies differentially a response signal v1(t) developed at the other end of the measuring object in response to the application of the probe signal w(t) and the probe signal w(t). The detecting unit detects capacitance change of the measuring object based on the amplified signal v(t) from the differential amplifying circuit.
