研究表明，电荷泵（CP）控制锁相环（PLL）的单粒子瞬态（SET）响应。采用脉冲表示单粒子撞击CP，建立了SET分析模型，揭示了SET在PLL中的产生和传播特性。PLL中的单粒子瞬态分析表明，单粒子撞击后压控振荡器（VCO）控制电压的建立时间强烈依赖于峰值控制电压偏差、SET脉冲宽度和建立时间常数。峰值控制电压扰动随SET强度或滤波电阻的增大而减小。此外，在所提出的PLL模型的分析证实了使用MATLAB和HSPICE的仿真结果，分别。
It has been shown that charge pumps (CPs) dominate single-event transient (SET) responses of phase-locked loops (PLLs). Using a pulse to represent a single event hit on CPs, the SET analysis model is established and the characteristics of SET generation and propagation in PLLs are revealed. An analysis of single event transients in PLLs demonstrates that the settling time of the voltage-controlled oscillators (VCOs) control voltage after a single event strike is strongly dependent on the peak control voltage deviation, the SET pulse width, and the settling time constant. And the peak control voltage disturbance decreases with the SET strength or the filter resistance. Furthermore, the analysis in the proposed PLL model is confirmed by simulation results using MATLAB and HSPICE, respectively.
