Modeling and analysis of single-event transients in charge pumps
电荷泵中单粒子瞬变的建模与分析

It has been shown that charge pumps(CPs)dominate singleevent 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...
