Abstract: A capacitive measuring system includes capacitive sensors and an evaluation circuit having a multiplexer, a synchronous rectifier, a sinusoidal signal generator, and a reference voltage divider. The capacitive sensors are acted on by a mono-frequency voltage signal generated by the sinusoidal signal generator, output signals of the capacitive sensors are transmitted in alternation to the synchronous rectifier via the multiplexer, and signal amplification of output signals of the synchronous rectifier are calibrated as a function of an activatable reference impedance. The synchronous rectifier is formed by a MOS semiconductor switch. A source-drain section of the MOS semiconductor switch forms a shunt that is controlled by the mono-frequency voltage signal. A channel of the multiplexer is provided for transmitting a calibration signal, generated by the reference voltage divider, to the synchronous rectifier alternately with the output signals of the capacitive sensors.

Abstract: A capacitive multipath force sensor module includes a movable actuator, first and second stationary capacitor plates, and a central capacitor plate connected to the actuator and positioned between the stationary plates. The central plate moves by a same amount toward one stationary plate and away from the other stationary plate when the actuator is moved. In multiple successive cycles, while the first stationary plate is held at ground, (i) the central plate and the second stationary plate are connected to a voltage and (ii) are then disconnected from the voltage with the central plate being connected to a capacitor having a known capacitance value to thereby enable a charge quantity stored on the central plate to be transferred to the capacitor. After a predefined number of cycles, a voltage of the capacitor, which is indicative of an amount of movement of the actuator, is measured.
