how to measure current mismatch in charge pump output?

[anushkannan81]

Hi i am designing charge pump for a PLL using tanner. i got the output. but i need to know how to measure current mismatch. In research papers , graph is plotted between output voltage versus output current. how to obtain simulation output , a graph between output voltage versus output current using tanner. Kindly help me.

Hey anushkannan81, do you find the solution ? I also have the same question. How to plot this graph ?

Hey kr_13, i am searching for it, and do you know the general mathematical flow for the current mismatch?
