I have a multiphase frequency divider that divides frequency by (67+1/6), (67+2/6),.... There are six equispaced phases at its input. The output is periodic but there are some picosecond order error in the consecutive time periods, i.e. the periods are like T+Δt₁, T-Δt₂, etc. However the ouput is exactly periodic with period of 6T.
Is there a way to remove the picosecond errors by adding an external circuit so that the period comes down to original T.
