A lot of texbooks don't teach Composite Amplifiers, but they are one of the most used circuit configurations to solve real world design poblems where you have multiple conflicting specifications.
00:00 - Composite vs Compound Amplifiers
02:53 - How a Composite Amplifier works
05:09 - Why not just cascade them?
07:23 - This doesn't just apply to opamps
08:24 - An example with gain, and another way to look at it
09:37 - Composite gain vs stage gain
11:19 - What's the catch? + rule of thumb for stability
12:42 - Another example: Composite precision high bandwidth amplifier
14:50 - Breadboard demonstration of Composite vs Compound amplfiers
19:09 - Changing to Composite configuration and Magic Happens
20:07 - More magic as it compensates for the buffer drop too
