Abstract: A charge sensing circuit generates a voltage in a sensing period that is indicative of sensed charge. The generated voltages are accumulated by an accumulator circuit over a number of sensing periods. A noise detection circuit senses when the voltage generated by the charge sensing circuit is outside of a boundary and generates a detection signal in response thereto. A control circuit, in response to the detection signal, controls the accumulator circuit to block accumulation of the voltages generated by the charge sensing circuit during at least the sensing period in which the detection signal is generated. An analog-to-digital converter circuit then converts an accumulated output voltage from the accumulator circuit to a digital value at the end of an accumulation time period that includes the sensing periods. The end of the accumulation time period is delayed by at least one sensing period in response to the detection signal.

Abstract: A touch screen controller is for a drive line emitting a periodic signal and capacitively intersecting sense lines. A selection circuit, for each of a number of portions of the periodic signal equal to a number of the sense lines, couples a first subset of the sense lines to a first output path, and couples a second subset of the sense lines to a second output path, the second subset being sense lines not included in the first subset. Processing circuitry, for each portion of the periodic signal, measures a capacitance of the first output path, measures a capacitance of the second output path, and sums the capacitance of the first output path and the capacitance of the second output path. The processing circuitry determines a capacitance between each sense line of the first and second subsets and the drive line as a function of the sums.
