Abstract: Method and system are provided for evaluating linearity of a capacitive-to-digital converter (CDC) of a capacitive sensor integrated circuit chip. The evaluating employs multiple test capacitors, which may be on-chip with the CDC, and includes: obtaining capacitance values for the multiple test capacitors and parasitic capacitances of a first input A and a second input B to the capacitive-to-digital converter; applying the multiple test capacitors in multiple permutations to the first input A and the second input B, and for each of at least some permutations, determining an error between an expected output of the CDC using the obtained capacitance values and an actual measured output of the CDC; and determining linearity error for the CDC using the determined errors for the permutations of applying the multiple test capacitors to the first input A and the second input B of the CDC.

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.

Abstract: A connection of a hose clamp and a hose has a rubber-elastic ring that surrounds the hose detachably and with elastic pretension. The ring is positioned underneath a clamp strap of the hose clamp. The ring has radial hook-shaped first projections for locking the clamp strap of the hose clamp between the first projections by engaging across edges of the clamp strap. The first projections are formed on edges of the ring. The thickness of the ring in an area located axially between the first projections is 5% to 9% of the wall thickness of the hose.

The CMOS switch includes first PMOS and NMOS coupled transistors. The generator provides, via first and second outputs, first and second voltage levels, and includes second PMOS and NMOS transistors. The second PMOS transistor is series connected between VDD and a first bias source and the second NMOS transistor is series connected between VSS and a second bias source. The booster circuit, which is coupled to the generator between its outputs, and to the PMOS and NMOS gates of the CMOS switch, capacitively stores during off level first and second boost voltages, which are coupled to the PMOS and NMOS gates. The boost voltages are offset from VDD and VSS, respectively, each by approximately a threshold voltage of the respective transistor type.
