    摘要: A phase locked loop (PLL) circuit includes a first signal detector having a first input terminal configured to receive a varying first input signal, a second input terminal configured to receive a feedback signal that corresponds to the center of the input frequency, and an output terminal configured to provide an output signal corresponding to a phase difference between the first input and feedback signals. A delay estimator has an input terminal configured to receive the output signal from the first phase detector and in response thereto, output a phase difference estimation signal. A variable delay circuit has an input terminal configured to receive the phase difference estimation signal and in response thereto, phase shift the second input signal.

    摘要: A system for capacitive object recognition including a pair of electrodes, one of the electrodes having an adjustable parameter, and a controller modeling current pathways formed by interaction of an object with an electric field between the pair electrodes as a network of capacitors. The controller is configured to set the adjustable parameter to a first setting and to apply a set of alternating current voltages to the pair electrodes and measure a resulting first set of current values at each of the electrodes, configured to set the adjustable parameter to a second setting and apply the set of alternating current voltages to the pair of electrodes and measure a resulting second set of current values at each of the electrodes, and configured to determine values for up to all capacitors of the network of capacitors based on the first and second sets of current values.
