Clock driving circuit resistant to single-event transient

摘要

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.
