Broskie OTL
Default Broskie OTL

Broskie posted this new otl circuite on the Tub Cad Journal.
I am assuming it is just the output stage and would need
a differential input. Has anyone here built this yet ? I wonder
what the output impedience would be assuming just the local
feedback used.

The output impedance in Class A will be Rp/2*(1+) and in AB Rp/(1+) it is basically an ordinary inverted Futterman OTL.
