Abstract: The present disclosure relates to a high-speed and low-power successive approximation register analog-to-digital converter (SAR ADC) and an analog-to-digital conversion method. Binary redundancy reassembly is performed to improve a digital-to-analog converter (DAC) capacitor array included in the SAR ADC such that the total number of capacitors included in a capacitor sub-array of the DAC capacitor array is greater than the number of precision bits of the SAR ADC, and the total number of unit capacitors included in all capacitors when the total number of capacitors included in the capacitor sub-array is greater than the number of precision bits of the SAR ADC is equal to the total number of unit capacitors included in all capacitors when the total number of capacitors included in the capacitor sub-array is equal to the number of precision bits of the SAR ADC.

Abstract: The present disclosure discloses an electrical connector and a plug-in module. The plug-in module includes a base, a plurality of input terminals, a plurality of output terminals and a PCB module. The base includes a bottom plate, a front plate and a back plate, and a tongue plate extending from the bottom plate forward beyond the front plate; the plurality of input terminals are fixed to the back plate, and two ends of each of the input terminals extend respectively beyond a top end of the back plate and a bottom end of the bottom plate; the plurality of output terminals are fixed to the tongue plate and the front plate, and two ends of each of the output terminals extend respectively beyond a top end of the front plate and the tongue plate; and the PCB module includes at least one circuit board.

Abstract: The disclosure provides an electrical connector, its manufacturing method, and a communication device. The electrical connector includes an insulator, on which at least one docking socket is provided; a housing provided outside the insulator; a signal processing unit provided in the insulator; and a signal display unit comprising a signal display circuit board, at least one SMD (surface-mounted-device) LED electrically coupled to the signal display circuit board, and at least one connection terminal electrically coupled to an exterior circuit board or the signal processing unit.
