PLL-charge pump
This paper present a dynamic matched charge pump to achieve small current mismatch and resist the current variation.Small current mismatch means small spurs in pll,and the constant current can make us predict the bandwidth of the pll precisely.Circuits design is based on the SMIC 0.18 μm proces...
