摘要： Embodiments provide systems and methods for aligning the supply voltage signal applied to a power amplifier (PA) with the radio frequency (RF) output signal of the PA in a wireless device. The RF output signal is generated by applying a transmit signal to a transmit path of the wireless device. The supply voltage is generated by applying an envelope tracking (ET) signal, based on the transmit signal, to an envelope tracking (ET) path of the wireless device. Embodiments operate by estimating the delays of the ET path and the transmit path, and then controlling a relative delay between the transmit signal and the ET signal accordingly. In an embodiment, estimation of the delays of the ET path and the transmit path is done by correlating respective signals of each path.

摘要： Control circuitry for a touch panel includes a touch panel interface, a memory comprising touch positioning logic, and a controller in communication with the memory and the touch panel interface. The controller is operable, when the touch positioning logic is executed, to perform selected processing of the touch panel, including scanning a touch panel and determining a touch panel blob resulting from a touch, obtaining blob characteristics of the touch panel blob, and determining a position of the blob relative to the touch panel based on the blob characteristics. The blob characteristics can be adjusted to more accurately position the blob in circumstances where the blob is located near the edge of the touch panel, is in close proximity to another blob, or when the touch panel has variation in the received signal noise.

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。
