    Abstract: Provided are a semiconductor device and a semiconductor system, which can increase immunity against noises through tertiary correlated double sampling (CDS). The semiconductor device includes an amplifier that receives noise and a driving signal, resets for each predetermined period of the driving signal and samples the noise to generate first sampled noise. The first sampled noise includes multiple noise differences each occurring between consecutive reset points. A sampler performs second sampling and third sampling on the first sampled noise and performs fourth sampling on the second and third sampled noises. The first sampled noise includes first to third noise differences, the second sampled noise is a difference between the first and second noise differences, the third sampled noise is a difference between the second and third noise differences, and the fourth sampled noise is a difference between the second and third sampled noises.

    Abstract: A touch controller includes a controller receiving a display timing signal and generating a touch sensing control signal synchronously with the display timing signal. The touch controller also includes a sensing circuit driving a touch sensing array in response to the touch sensing control signal in order to generate touch data corresponding to sensing signals provided by the touch sensing array. The sensing circuit provides a first driving signal having a first polarity to at least one driving channel of the touch sensing array during a first display frame period, and provides a second driving signal having a second polarity different from the first polarity during a second display frame period.

    Abstract: A touch sensing device includes a touch panel and a receiving unit. The touch panel generates first to third receiving signals corresponding to a touch occurring at the touch sensing device. The receiving unit is connected to the touch panel through first to third receiving lines to receive the first to third receiving signals through the first to third receiving lines, respectively. The receiving unit includes a differential signal generator for excluding a first common signal common to the first and second receiving signals from each of the first and second receiving signals to generate first differential signals when a first touch sensing operation is performed. The differential signal generator excludes a second common signal common to the second and third receiving signals from each of the second and third receiving signals to generate second differential signals when a second touch sensing operation is performed.
