摘要： Asymmetric scanning logic implements asymmetric panel scanning by scanning some rows on a touch panel more frequently than other rows. Note that although an entire row at a time may be driven, if only particular pixels in the row are of interest (e.g., included in any region of interest for focused asymmetric scanning), then circuitry may power down the receivers for the columns in which the pixels exist to save power. The asymmetric scanning logic facilitates focused attention to specific areas of interest on the touch panel, to compensate, for example, for high noise or low signal strength in those areas of interest.
摘要翻译：非对称扫描逻辑通过比其他行更频繁地扫描触摸面板上的一些行来实现非对称面板扫描。注意，虽然可以驱动一次的整行，但是如果行中的特定像素是感兴趣的（例如，包括在用于聚焦的非对称扫描的任何感兴趣的区域中），则电路可以将其中的列的接收器断电存在像素以节省电力。非对称扫描逻辑有助于将注意力集中在触摸面板上的特定感兴趣区域，以补偿例如在感兴趣的区域中的高噪声或低信号强度。

摘要： A mode-configurable amplifier comprises a single-ended input for receiving a received signal from a capacitive touch panel, a differential output operable to carry a differential processed signal to a subsequent processing stage, and processing circuitry in communication with the single ended input and the differential output. The processing circuitry comprises mode selection inputs and mode selection circuitry in communication with the mode selection inputs. The mode selection circuitry is operable to configure the processing circuitry into a current operating mode selected from a high-pass filter mode, bandpass filter mode, and a trans-capacitive gain mode. The high-pass filter mode is operable to high-pass filter the received signal to obtain the differential processed signal. The bandpass filter mode is operable to bandpass filter the received signal to obtain the differential processed signal. The wideband gain mode is operable to amplify the received signal to obtain the differential processed signal.
