摘　　要：介绍了一种低功耗的抗辐照加固5 V1 Mbit.s-11553B总线差分接收器的研制,该电路可实现总线信号接收的功能。电路设计采用商用BCDMOS Process,不仅对总线上的高频噪声有滤波作用,而且对总线上的共模信号进行抑制,在解决输出脉宽、接收阈值、输出多脉冲、输出脉宽展宽、总线偏移等问题的同时,降低了芯片的功耗。此外,基于普通商用体硅BCD工艺线,通过版图设计对闩锁效应、场区和电参数的辐射效应进行加固。流片测试试验结果表明,电路的性能良好,可广泛用于1553总线系统。The development of a 5 V 1553B differential receiver which can perform anti-radiation and low power is presented,and the receiver can receive the signal on bus.The circuit based on commercial BCDMOS Process can not only filter the noise on bus,but also restrain the common signal.The receiver not only solve the problem of output pulse width,receiving threshold value,unnecessary output pulse and so on,but also lower the power dissipation.In addition,the design reinforces some sensitive parameters about radiation by the design of layout.The test result of the chip shows that the function of the chip is favorable,and can apply extensively to the system of 1553B bus.
