Abstract: A capacitive-to-digital converter is provided which includes: sensor, offset and reference capacitors, an integrator circuit and a demodulation circuit. The sensor capacitor is switched according to a first clock and the offset capacitor according to a second clock, which has a higher switching frequency. The reference capacitor is switched according to a return signal from the converter's output. The integrator circuit includes an integrator capacitor, and has first and second nodes, with the sensor, offset and reference capacitors each being switched to the first and second nodes based on the respective first clock, second clock or return signal. The demodulation circuit receives and converts output of the integrator circuit into a digital output. The higher frequency clocking of the offset capacitor allows for a reduction in capacitance of the offset, reference or integrator capacitor, and the multiclocking of the converter allows for use of a multireferencing to the sensor capacitor.

Abstract: An arrangement for digital measuring a capacitive sensor is provided with a charge balance frequency converter having an operational amplifier with an inverting input, a noninverting input and an output. Between the output and the inverting input an integrating capacitor is connected, and the noninverting input is connected with a reference potential. The arrangement provides a simple switched capacitor architecture for measuring the sensor capacitance, which tolerates grounded sensor capacitors, and which is not affected by the shunt resistance. The value of the shunt resistance is determined at the same time. The arrangement makes use of a two frequency measurement of the capacitor resistance combination by using the charge balancing procedure followed by a calculation based on the results of two conversions and the ratio of the clock frequencies of the first and second conversion.
