摘要： Methods, systems and devices are described for detecting a measurable capacitance using charge transfer techniques. According to various embodiments, a charge transfer process is performed for two or more times. During the charge transfer process, a pre-determined voltage is applied to the measurable capacitance, and the measurable capacitance is then allowed to share charge with a filter capacitance through a passive impedance that remains coupled to both the measurable capacitance and to the filter capacitance throughout the charge transfer process. The value of the measurable capacitance can then be determined as a function of a representation of a charge on the filter capacitance and the number of times that the charge transfer process was performed. Such a detection scheme may be readily implemented using conventional components, and can be particularly useful in sensing the position of a finger, stylus or other object with respect to an input sensor.

摘要： Methods, systems and devices are described for detecting a measurable capacitance using sigma-delta measurement techniques. According to various embodiments, a voltage is applied to the measurable capacitance using a first switch. The measurable capacitance is allowed to share charge with a passive network. If the charge on the passive network is past a threshold value, then the charge on the passive network is changed by a known amount for a sufficient number of repetitions until the measurable capacitance can be detected. Such a detection scheme may be readily implemented using conventional components, and can be particularly useful in sensing the position of a finger, stylus or other object with respect to a button, slider, touchpad or other input sensor.

摘要： Embodiments of the present invention generally provide a method and system for sensing interference in a display device having integrated input sensing. In various embodiments of the invention, input sensing performed on one or more rows of common electrodes may be operated for interference sensing, and, during the blanking period, some or all of the common electrodes may be operated for interference sensing. Interference measurements acquired during blanking periods may be used to increase the accuracy with which input sensing is performed, for example, by establishing one or more baseline interference values and/or determining that one or more common electrodes should be driven at a different frequency. In some embodiments, all of the common electrodes may be operated for interference sensing during a blanking period, while in other embodiments a portion of the common electrodes (e.g., one-third, one-half, etc.) may be operated for interference sensing during a blanking period.
