Abstract: A wearable electronic device is provided. The wearable electronic device includes a touch display panel, a touch bezel and a processor. The touch display panel is configured to sense at least one first touch event and display content. The touch bezel is disposed around the touch display panel and configures to sense at least one second touch event. The processor is configured to generate at least one control signal according to a combination of at least one scenario occurring on the touch display panel and the at least one second touch event, and control the wearable electronic device to perform at least one operation in response to the at least one control signal.

Abstract: A method for evaluating capacitor weighting of an analog-to-digital (ADC) is provided. An equivalent weighting value of each composed capacitor in each sub-capacitor-array may be obtained by adding the switch device to the ADC which enables each sub-capacitor-array in a digital-to-analog (DAC) to be measured by each other. The ADC can calculate and then obtain a correct digital output by using the calibrated equivalent weighting and successive approximation result of each input signal.

Abstract: A method and an apparatus for evaluating weighting of elements of a DAC and a SAR ADC using the same are provided. An equivalent weighting of each composed element is obtained by adding a reference element with a reference weighting, an auxiliary DAC, and a search circuit into the SAR ADC, and the equivalent weighting is represented by the reference weighting. The SAR ADC can calculate and then obtain a correct digital output by using the calibrated equivalent weighting and the successive approximation result of each input signal. The present disclosure prevents the necessity of matching each composed element of the DAC in the SAR ADC.

Abstract: A successive approximation register analog to digital converter (SAR ADC) and a method of linearity calibration therein are provided. Each composed element Ei in a part of the composed elements includes a main constructed element Ei0 and wi sub constructed element Ei1, Ei2, . . . , Eiwi. The SAR ADC selects a part of the sub constructed elements Ei1, Ei2, . . . , Eiwi and make them non-functional when a missing decision level is caused by the composed element Ei. An overlap cancellation to the obtained missing code numbers is performed, compensation coefficients are updated according to the missing code numbers after the overlap cancellation, and a compensation to the corresponding digital value is performed according to the compensation coefficients. The present disclosure prevents the necessity of matching each composed element of the DAC in the SAR ADC.
