Title: ANTI-SINGLE EVENT TRANSIENT CLOCK TREE STRUCTURE
Abstract:
An anti-single event transient clock tree structure, comprising root node clock drive units, sub-node clock drive units, and leaf node clock drive units, the root node clock drive unit and the sub-node clock drive unit both being a clock inverter or buffer, and the leaf node clock drive unit being a dual-path filter; the dual-path filter can eliminate single event transient pulses that occur on the input signal and have a pulse width less than the delay time internally set in the filter, the same input signal outputting two paths of output signal that do not mutually interfere. Each dual-path filter drives a certain number of dual clock anti-single event timing units. The present invention significantly improves the anti-single event transient capability of a clock tree network, effectively reduces the probability of single event transient pulses on any clock node and multiple clock tree nodes when the clock tree network is bombarded by radiating particles, and has low power consumption, fast speed, and a small area relative to integrated circuits implemented in timing unit single particle transient reinforcement methods.
