Abstract:

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.
