Abstract: A support structure for supporting a computer device includes a clamping frame, two clamping members, and a support rod. The clamping frame is used for clamping a side of the computer device. The two clamping members are disposed on the clamping frame. At least one of the two clamping members has at least one angle positioning bump. The support rod is disposed at a side of the clamping frame for supporting the clamping frame. The support rod includes an arm portion and a shaft portion. The arm portion has an angle positioning hole for engaging with the angle positioning bump to fix an angle of the arm portion relative to the clamping frame. The shaft portion is extendedly connected to an end of the arm portion and detachably disposed between the clamping members, for making the arm portion capable of rotating relative to the clamping frame.

Abstract: A successive approximation register (SAR) analog-to-digital converter (ADC) is disclosed. A first and second capacitor DACs receive a first and second input signals respectively. A first coarse comparator compares an output of the first capacitor DAC with a window reference voltage, a second coarse comparator compares an output of the second capacitor DAC with the window reference voltage, and a fine comparator compares the output of the first capacitor DAC with the output of the second capacitor DAC. A SAR controller receives outputs of the first and second coarse comparators to determine whether the outputs of the first and second capacitor DACs are within a predictive window determined by the window reference voltage. The SAR controller bypasses at least one phase of analog-to-digital conversion of the SAR ADC when the outputs of the first capacitor DAC and the second capacitor DAC are determined to be within the predictive window. The SAR controller decodes the outputs of the first and second coarse comparators and the fine comparator to obtain a converted output of the SAR ADC.
