Optimos - My Version

[Magna]

Here is my first attempt on amp design. Instead of making a completely new design, i used "optimos" by randy as base and started fitting in my requirements. Based on Bob's book on amp design, i've redesigned the output stage with Vertical fets and changed the Compensation from TPC to TMC. Also few component values are changed to enhance slew rate, stability etc.,. I've acheived a THD-20 as 0.014% at Max. power.

Any comments...?
