Hi,
Is it possible to have a current mirror to feed the output stage in the aleph 3? Any benefit?

What do you want to use the current mirror for? To what purpose? The Aleph-current source can be seen as a single transistor gain stage with a single transistor current source - it's just the real world that needs some paralleled fets in this position.

Perhaps you would like to post a picture of what you have in mind
for greater clarity. There are a couple of ways to interpret "current
mirror"

This is unlike current mirrors with which I am familiar.

Maybe you want to rework your drawing a bit, at the moment it looks more like a signal modulated cascode 😉
May I ask you what your idea behind using a current mirror is? More gain and more feedback? Or just playing around a bit?

Just playing around.
You mean by having emitters and collectors reversed, right?originally posted by h_a

Is it not the same fashion as the output stage (the sources feeding the drains) ?originally posted by Nelson PassThis is unlike current mirrors with which I am familiar.
Hi,
Yup, and you maybe want also to think a bit about what a current mirror is and does...it's an active load. But you have already a load resistor drawn...
<the sources feeding the drains>
Reading the Aleph-owner's manual will help you understand the amp better 😉
