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: An electromagnetic field simulation method based on subgridding technique and one-step alternating-direction-implicit-finite-difference time-domain (ADI-FDTD) algorithm is provided herein. The method includes establishing an electromagnetic field simulation model by setting an absorption boundary condition, a periodic boundary condition, a total field boundary condition and a scattering field boundary condition based on the one-step ADI-FDTD algorithm, subgridding technique and FDTD algorithm. The electromagnetic field simulation model is configured to select a detection point and a detection surface, obtain a time-domain waveform diagram of a reflection field of a simulation area, a time-domain waveform diagram of a transmission field of the simulation area and frequency-domain information of the simulation area, and simulate an electromagnetic field, by the electromagnetic field simulation model.

Abstract: Systems and methods for identifying three dimensional (3D) content to stream. A method includes receiving information indicating a view field of a client device and identifying an amount of bandwidth available to stream the 3D content to the client device. The method includes assigning, for one or more of the objects, the bandwidth by, for each of the objects: determining whether the each object is within the view field of the client device based on a position of the each object; assigning a greater amount of the bandwidth to objects at least partially within the view field. The method includes streaming the 3D content to the client device according to the assigned bandwidth.
