Abstract

The invention provides a single-particle-resistant transient pulse CMOS (complementary metal oxide semiconductor) circuit. The single-particle-resistant transient pulse CMOS circuit comprises a first buffer (101), a second buffer (102), a gating PMOS (P-channel metal oxide semiconductor) transistor (103), a gating NMOS (N-channel metal oxide semiconductor) transistor (104) and a phase inverter (105), wherein the first buffer is used for eliminating 'high-low-high' type pulses; the input end of the first buffer is connected with the input end of a single-particle-resistant transient pulse circuit; the output end of the first buffer is connected with a grid electrode of the gating PMOS transistor (103); the second buffer is used for eliminating 'low-high-low' type pulses; the input end of the second buffer is connected with the input end of the single-particle-resistant transient pulse circuit; and the output end of the second buffer is connected with a grid electrode of the gating NMOS transistor (104). A drain electrode of the gating PMOS transistor (103) is connected with a drain electrode of the gating NMOS transistor (104) and serves as the input end of the phase inverter (105); and the output end of the phase inverter (105) serves as the output end of the single-particle-resistant transient pulse circuit.
