摘要： A capacitive sensing analog front end for a touchscreen system having an improved signal-to-noise ratio includes a capacitance-to-voltage converter having an input for coupling to an external sampling capacitor, a summer having a first input coupled to an output of the capacitance-to-voltage converter, a low pass filter having an input coupled to an output of the summer and an output for providing an output signal; and a sample-and-hold circuit having an input coupled to the output of the low pass filter and an output coupled to a second input of the summer. The signal-to-noise ratio of the touchscreen system is improved by extracting the DC shift of a touch signal during a monitoring period and then subtracting the DC shift before integrating the touch signal.

摘要： A method of matrix sensing using delay-based capacitance sensing, including using X-axis lines as active lines for capacitance measurements and using Y-axis lines as a disturbance to identify the location of a touch in a key matrix is disclosed. A sensing signal is applied to the X-axis lines, and a disturbance signal is applied to the Y-axis lines. If a location is touched, cross-capacitance is reduced, which is measured by sweeping data along the X-axis lines.

摘要： A capacitive touch sensor includes horizontal lines vertical lines. Switching circuitry is coupled to the horizontal and vertical lines of the capacitive touch sensor. The switching circuitry is operable in a first mode to configure the horizontal lines as receive lines and the vertical lines as transmit lines for making a cross-capacitance measurement. In one implementation, the switching circuit is further operable in a second mode to configure the horizontal lines as transmit lines and the vertical lines as receive lines for making an additional cross-capacitance measurement. In another implementation, the switching circuit is further operable in a second mode to configure the vertical lines for making a self capacitance measurement. The various capacitance measurements from the first and second modes are algorithmically combined to obtain a total capacitance measurement having a reduced noise component.

摘要： A noise suppression method for a capacitance-to-voltage converter varies a sequence of sensing signal edges during a plurality capacitance measurements to produce a number of noise responses. The sensing signal edges are varied in a repetitive rising and falling edge pattern for each sequence. Three or more such sequences can be used, and the sequence with the highest noise is eliminated and the others are averaged. The noise suppression method can be implemented during calibration and then used for a number of normal acquisitions. The noise suppression method can be applied to capacitance-to-voltage converters having monitoring and integration phases.

摘要： A touch screen capable of correctly identifying multiple touches employs multiple active line arrays oriented to provide multi-dimensional data. Three arrays of capacitance based active lines are each distinctly oriented to form a plurality of intersections. A first and second array are generally oriented perpendicularly while a third array is oriented to bisect the resulting matrix such that the active lines of the third array also intersect the existing vertices. As a result of a touch each active line array identifies the location of the touch from three distinct directions. Ambiguity from dual touch scenarios existing in dual array systems is removed by providing an additional reference.

摘要： A touch controller processes a captured data frame and detects the presence of touch points in the data frame. The data frame includes a plurality of digital capacitance values organized as groups of sense line data and the touch controller determines for each digital capacitance value in a group of sense line data the difference between the digital capacitance value and an associated no-touch threshold to generate a baseline delta value for each digital capacitance value in the group. The touch controller selects the minimum baseline delta and adjusts each digital capacitance value in the group by the minimum baseline delta to generate adjusted sense line data. The touch control generates adjusted sense line data for each group of sense line data in the data frame and thereafter processes the groups of adjusted sense line data to detect the presence of touch points in the data frame.
