Allison(ish) driver/bias stage for Mosfets

[godfrey]

Driving a Mosfet output stage with an Allison should allow greater output voltage swing since you're not losing Vgs on either side.

Adding a couple of transistors for current gain (Q1 and Q2 below) makes it a really easy load for the VAS too.

Looks good to me! What am I missing?

Looks good to me, too

He he,

Symmetrical Bootstrap and Darlington VAS, that,s nearly a jack of all trades.

I use a bi-polar bootstrap to power driver stage for source follower mosfets, it works great.🙂
