Yes correct thanks for noticing.@WhiteDragon is a few people that know the topology well. He only puts the miller cap on the one side of VAS.
If you see there 2 miller caps on both sides of differential VAS, the designer doesn’t really know what he/she is doing.
And often can cause stability issues at high frequency if both caps are used.
With Quasi being half CFP its good idea knowing this topology well before wildly guessing and gluing whatever output section
you want on there.
Long tail pair is 1ma with required Degen to also keep stability rather tame. And the input currents are rather linear over a wider
voltage range. No stability issues
Feedback current source is close to 1meg impedance but using the zener and higher voltage reference brings it closer to 2meg impedance.
thermal stability is completely opposite as peoples assumptions it is actually more stable over wide temperature range.
I wont waste much time arguing about it, for outputs put what you want in there then. Or just krank up the voltage for more power
it is ready for it.
