Phase-Dependent Single-Event Sensitivity Analysis of High-Speed A/MS Circuits Extracted from Asynchronous Measurements

A method for experimental determination of the phase dependence of single-event sensitivity in high-speed A/MS circuits is presented. The technique ensures testing coverage of the complete data cycle and results in a correlation of errors to the data or clock cycle of the circuit. Designers can apply the information, along with knowledge of the circuit state at the time of errors, to make informed radiation-hardening-by-design decisions.
