I am making a design for a charge pump, and i want to eliminate the mismatch current as much as i can, but the problem is when i made a current mirror with a same (W/L) then the the current i got from the mirror was not equal to the source current, i.e the source current is (5u A) and the mirror current is (5.4u A), so what is the problem and what can i do
the second question is: what is the advantage of putting an op-amp in the architecture of the charge pump, and where i can get the schematic of the op-amp
thanks in advance
