Abstract: An in-cell touchscreen panel includes columns of transmit electrodes and rows of sensing electrodes, wherein each row of sensing electrodes comprises a first subset of sensing electrodes coupled to control circuitry via a first subset of receiving traces and a second subset of sensing electrodes coupled to the control circuitry via a second subset of receiving traces. To enable multi-touch functionality, the in-cell touchscreen panel operates in a scanning mode where capacitance is measured at each node where the sensing electrodes intersect the transmit electrodes. During the scanning mode, the control circuitry senses the first and second subsets of receiving traces while applying drive signals to pairs of transmit electrodes. After a drive signal has been applied to each of the transmit electrodes, each of the nodes are measured to detect a capacitance. This capacitance is indicative of a user touch on the in-cell touchscreen panel.

Abstract: Accumulators that operate to fully or partially remove noise from a signal, including removing noise inserted into the signal by the accumulator itself. In some embodiments, an accumulator may be operated in a sampling phase and a transfer phase each time the accumulator samples an input signal. In some such embodiments, an op-amp of an accumulation circuit of the accumulator may be auto-zeroed during some or all of the sampling phases of an accumulation period. In some embodiments in which the op-amp is auto-zeroed during some or all of the sampling phases, the accumulation circuit may include a holding capacitor that, during an auto-zeroing process, holds a value output by the op-amp during a prior transfer phase. Including such a holding capacitor in an accumulator may reduce a voltage that the op-amp output rises following the auto-zero process, which may reduce a bandwidth and noise of the accumulation circuit.
