外文摘要：A radiation-hardened phase-locked loop is proposed for phase interpolator clock and data recovery purposes.A sensitive node-compressed charge pump and multi-node cross coupling voltage-controlled oscillators are proposed in this phase-locked loop with the goal of achieving good jitter performance and improving anti-SET(SET,single-event transient)capability.The root mean square(RMS)jitter of the phase-locked loop is reduced from 3.7 ps to 2.58 ps at 2 GHz,while the laser threshold is improved from 120 pJ to 370 pJ compared to the unhardened phase-locked loop.The hardened phase-locked loop also does not lose its lock state from linear energy transfers(LETs)of 3.3 to 37.3 MeV·cm2/mg.
