Single event transient pulse resisting CMOS circuit

Abstract

The invention provides a single event transient pulse resisting CMOS circuit which comprises a first buffer and a second buffer. The input end of the first buffer is connected with the input signal of the first buffer, and the output signal of the first buffer is connected with the data input end of a first transmission door. The input end of the second buffer is connected with the input signal of the second buffer, and the output signal of the second buffer is connected with the data input end of a second transmission door. The data output signal of the first transmission door is connected with the data output end of the second transmission door and the input end of a first phase inverter. The output signal of the first phase inverter is connected with the input end of a second phase inverter, the grid electrode of an NMOS tube in the first transmission door and the grid electrode of a PMOS tube in the second transmission door. The output signal of the second phase inverter is connected with the grid electrode of a PMOS tube in the first transmission door and the grid electrode of an NMOS tube in the second transmission door and is used as the output signal of the single event transient pulse resisting CMOS circuit. According to the single event transient pulse resisting CMOS circuit, the buffers with different pull-up / pull-down capacities are used for filtering two classes of single particle pulses, the corresponding signals are output by controlling the transmission doors, and the single event transient pulse resisting CMOS circuit has the advantages of having few MOS tubes, being strong in single event transient pulse resisting capacity and good in filtering effect and the like.
