In very simple words source degeneration reduces gm of the MOS hence improves matching. Another way to look at it is by adding resistor you are making it closer to a V/R circuit. And since resistors are much better matched as compared to MOS, overall matching improves.
crisp and clear explanation... waiting for a continuation video for this video... :-)
Very well explained. Thanks a lot. Waiting for some Cascode current mirror design guidelines.
Great Tutorial, thank you, Sir!
Nice Video. Can you explain how Source degeneration improved matching? Thanks

Can you please elaborate on why we cannot generate more than one output current branches in willson current mirror topology?
How about stacked mos topology.. ?? In that case what could be the effective gm? Please let me know.
