    摘要: An automatic self-calibrated oscillation method and an apparatus using the same are provided. After a static time tuning (STT) table and a run time tuning (RTT) table have been established, the apparatus converts an output clock signal to generate a current RTT value at every predefined time and then compares the current RTT value with a reference RTT value generated in response to a STT value of the STT table, or with an interpolated result generated in response to the reference RTT value to generate a deviation value. Thus, through the deviation value, the output clock signal may be calibrated to address the target frequency without the assistance of external reference clock unit or locked loop unit after the STT table and the RTT table are established.

    摘要: A method of reducing computation of palm rejection by projecting touch data is disclosed, targeting the handheld devices. The method targets first at obtaining a difference array, followed by extracting maximum values of rows and columns of the difference array to obtain a row projection list and a column projection list respectively. By repeated implementing of mutual capacitance detection, ghost palm blocks can be wiped out from the multiple palm blocks. Once integrating with a local spatial boundary detection algorithm, the sensed signals of intended input located within a rectangular palm block yet beyond a real palm block are consequently detected. The computational algorithm of the palm rejection of this invention is successfully built into the touch panel controller due to its substantially reduced computation.
