The present disclosure discloses a Single-Event Transient (SET) pulse measuring circuit capable of eliminating impact thereof, and an integrated circuit chip. The SET pulse measuring circuit capable of eliminating impact thereof includes four parts: a SET pulse test chain, a latch circuit, a flip-flop test circuit, a latching self-trigger circuit. The integrated circuit chip is provided with a test chain module and two sets of SET pulse measuring circuits capable of eliminating impact thereof, and inputs of the two sets of SET pulse measuring circuits capable of eliminating impact thereof are the same and each are connected to an output terminal of the test chain module.

Single-event transient (SET) pulse measuring circuit capable of eliminating impact thereof, and integrated circuit chip

Disclosed in present invention is a clock driving circuit resistant to single-event transient. The clock driving circuit resistant to single-event transient consists of two kinds of inverters: double-input double-output (DIDO) inverter and double-input single-output (DISO) inverter, the specific number of the two kinds of inverters used, and the connection way thereof are determined by the complexity of a designed circuit and a clock design method used by the designed circuit. The DIDO inverter and DISO inverter both comprise two PMOS transistors and two NMOS transistors. In a clock distribution network based on double-input double-output and double-input single-output clock inverters, the probability that single-event transient pulses generated on the DIDO inverter are propagated to clock leaf nodes is zero. Therefore, the invention effectively reducing the probability that the clock distribution network generates single-event transient pulses on the respective clock leaf nodes after being bombarded by radiation particles.
