摘要： Methods, systems and devices are described for detecting a measurable capacitance (112) 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 (112), and the measurable capacitance (112) is then allowed to share charge with a filter capacitance (110) through a passive impedance (Z) that remains coupled to both the measurable capacitance and to the filter capacitance (110) throughout the charge transfer process. The value of the measurable capacitance (112) can then be determined as a function of a representation of a charge on the filter capacitance (110) 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 (Cx) using sigma-delta measurement techniques. According to various embodiments, a voltage is applied to the measurable capacitance (Cx) using a first switch. The measurable capacitance is allowed to share charge with a passive network. If the charge on the passive network (109) is past a threshold value, then the charge on the passive network (109) is changed by a known amount for a sufficient number of repetitions until the measurable capacitance (Cx) 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： An input device processing system comprises a sensor module that transmits a first transmitter signal with a transmitter electrode and receives a resulting signal with a receiver electrode. The first transmitter signal comprises a first transmitter frequency, and the resulting signal comprises effects corresponding to the first transmitter signal. A demodulation module demodulates the resulting signal to produce a first signal (e.g., an upper sideband signal) and a second signal (a lower sideband signal), selectably determines a first measurement of a change in capacitive coupling between the transmitter electrode and the receiver electrode based on at least one of the first and second signals, and determines positional information for an input object based on the first measurement.

摘要： Methods, systems and devices are described for detecting noise in a sensor that produces an output in response to a stimulus applied at or near a sensing region. A carrier signal is applied to the sensing region at two or more frequencies to produce an output at each frequency that is demodulated and filtered by a demodulation filter. The various frequencies applied to the carrier signal are selected such that a frequency difference is less than the demodulation filter bandwidth. At least some of the stimulus effects are removed from the outputs produced by the various carrier frequencies to produce two or more filtered outputs. The filtered outputs are then processed to detect noise contained therein. If noise contained in one or more of the filtered outputs reaches an unacceptable level, the carrier signal is shifted to a new sensing frequency for subsequent operation.

摘要： In a method of determining interference in a capacitance sensor, a signal is transmitted on a transmitter sensor channel of the capacitive sensor. The signal is received on a receiver sensor channel of the capacitive sensor, the receiver sensor channel being coupled with an amplifier. Behavior of the amplifier is examined for non-linearity to determine if a level of interference has been received by the receiver sensor channel in conjunction with receipt of the signal.
