  • Patent number: 12282626
    Abstract: A test method for a combination of touch sensitive processing apparatus and touch panel. The test method is configured to find out whether a stored time difference value with regard to driving signals is appropriate for the combination. If not, the test method is further configured to test several candidate time difference values for finding out one or a best one, which can be stored in a non-firmware of a non-volatile memory as a parameter for further touch sensitive processing. When none of the candidate time difference values is appropriate, the combination is determined as disqualified.

  • Patent number: 11693089
    Abstract: A system includes a local oscillator (LO) signal generation circuit, a receiver (RX) circuit, and a calibration circuit. The LO signal generation circuit generates an LO signal according to a reference clock, and includes an active oscillator that generates the reference clock. The active oscillator includes at least one active component. The RX circuit generates a processed RX signal by processing an RX input signal according to the LO signal. The calibration circuit checks a signal characteristic of the processed RX signal by detecting if a calibration tone exists within a receiver bandwidth, set a frequency calibration control output in response to the calibration tone being not found in the receiver bandwidth, and output the frequency calibration control output to the LO signal generation circuit. The LO signal generation circuit adjusts an LO frequency of the LO signal in response to the frequency calibration control output.
