Re: Precision current mirror


snip

I guess Jim could answer this but, if you got 3 transistor in a
package
on a single die I assume, and made a one to two transistor in
parallel
mirror how well would they match and track?

The main problem with the simple 3 transistor current mirror is that
it produces a current "sink" from the original current "source"

To produce a matching current "source" from another "source" you need
a more complex arrangement.
