After a long search I have found a description of the circuit in
question. It is the Sziklai configuration. The circuit in question is at
http://www5b.biglobe.ne.jp/~houshu/synth/EgMos0210a.GIF
involving Q7 and Q8. The designer has selected the two transistors where
the dominant feature appears to be that Hfe does not change with
variation in emitter current. Equivalent types are KSA733 and KSC945.
What is the advantage of using a transistor with constant Hfe in this
configuration? Is there also an advantage when used in the Darlington
configuration?
TIA, f
