SRAM (Static Random Access Memory)-based FPGA (Field-Programmable Gate Array) is widely used in aircraft with its high-performance and reconfigurable characteristics. It has been proved that SRAM memory cells of the device are extremely sensitive to single particle effects of atmospheric neutrons. SEU (Single Event Upset) failure chain was proposed according to the SRAM-based FPGA three-tier architecture...
A planar compact contiguous-channel substrate integrated waveguide (SIW) multiplexer (MUX) is proposed in this paper. To reduce the size of the MUX, the output channels are closely aligned to each other through the use of a compact SIW power combiner. To develop the proposed MUX with high efficiency and high accuracy, a systematic design procedure using an aggressive space-mapping (ASM) optimization...
This paper presents an efficient way to implement an interpolation filter in 18bit Σ-ΔDAC. The filter based on multiterm interpolation principle, to over-sample (128×)the audio singal with the sample rate of 48kHz and the resolution of 18 bit. After system simulated in the matlab, implemented with VerilogHDL, the circuit is designed and simulated with Quartus II. The simulation result illustrates...
Battery peak power capability estimation has an important theoretical significance and utility value for proper use of a battery and to help extend its lifetime. It is an important part of a battery management system. The paper presents an algorithm for estimating the dynamic peak power capability of a battery pack. The algorithm is based on a dynamic battery model taking into consideration constraints...
