Patent DE-19945330-A1 (DE)
Inventor: WINKENS FRANK
IPC: H03K17/955
Filed: 1999-09-22
Abstract: The invention relates to a method for detecting and evaluating small capacitance variations for converting into a switching signal, using an electric amplifier (1), whose positive or negative supply terminal is connected to a positive or negative direct current voltage source and whose other supply terminal is connected to a reference potential. An electrode (2), which is positioned so that it can be displaced in relation to an object (3) that is to be sensed, is connected to the input of the amplifier. An alternating voltage signal consisting of positive and negative half-waves, such as a common-mode signal or a square-wave signal is applied to the supply terminals of the amplifier (1), in such a way that the supply voltage of the amplifier remains constant but that the amplifier (1) and electrode (2) pass through a voltage swing in the common-mode of the positive and negative half-waves of the alternating voltage signal. During the sensing of an object (3), a signal (electrode signal) which emanates from the electrode (2) is amplified in the amplifier (1) and this amplified alternating voltage signal which appears at the output of the amplifier (1) is subsequently rectified in a rectifier circuit, decoupled from the alternating voltage, earthed and used as direct current or continuous current for evaluation. The rectified, amplified alternating voltage signal to earth is directly dependent on the magnitude of the reactance between the electrode (2) and the object (3).
