A radiation hardening algorithm named as state-conservation on 2nd order clock and data recovery (CDR) system is presented in this paper. This proposed algorithm is used to resist the single event transient (SET) of CDR tracking loop. A MATLAB model is established to fast evaluate the sensitive position of the system. A circuit model of 5 Gbps half rate CDR together with the hardening algorithm is set up to verify the effect of the proposed algorithm in Cadence design environment. The simulation result shows that SET does not lead to any error data and no loop delay is added. Compared to the RHBD standard-cell technique, the hardening algorithm saves area about 15.3% and reduces power consumption about 47.8%.
