This is an idea to mix two concepts. And the result is not to bad. But this Amp is definitely not for capacity load, then it tends to oscillate. A output filter is recommended.
Because of the last voltage amplification the amp can power up from rail to rail.
The simulated THD is about 0.000015% 🙂

Hi Pawel,
It's just a spontaneous idea, I will not further pursue this 🙂
At the time I am developing a module for an active Box. It should have:
-low Bias
-soft clipping
-short circuit protection
-rail to rail
-and, of course, acceptable performance
There must be an alternative to the LM ... and TDA ...

I really like the VSSA but has it
-low Bias (about 15mA for whole amp)
-soft clipping
-short circuit protection
-rail to rail

If you connect the LTP cascode reference voltage V1 to the current source (collector of Q2) rather than ground, I believe it will reduce the common-mode distortion produced in the non-inverting configuration by modulation of the C-E voltage of the input pair, despite their cascode.
