一种用于FPGA配置的抗干扰维持电路
Antijamming Holding Circuit for FPGA Configuration Cell
摘要
Abstract
An antijamming holding circuit is proposed to solve the problem with data losing under the noise in the SRAMbased FPGA configurafion cell. When the structure parameters of the area efficient configuration cell designed, the Static Noise Margin(SNM) of configuration cell increases as the power supply voltage increases. Through the detailed design of the voltage reference,charge inmr mp and voltage comparation circuit,we realized a feedback controlled steady power supply for FPGA configuration cell. Simulation and testing results show,an FPGA with the new structure can hold data in configuration cell under the 1.8V voltage while its normal voltage supply is 2.5V,which improve the antijamming performance of FPGA.关键词
