Hi Thorsten,the term "diamond transistor" was coined by Burr Brown, if I remember correctly. I guess you are referring to the four transistor emitter follower that is found both as an output stage and as a buffer to the non-inverting input of most current feedback op-amps?
This design has excellent slewing performance, but usually has a THD in the -90 to -100 dB range, provided that device matching is excellent and loading low.
I use it as a buffer to a discrete bipolar VFB amp. Inherent low distortion plus some overall voltage feedback makes a good preamp.
Greetings,
Eric
