This comparator is not dynamic (i.e., clocked latch).
Only the middle stage is of regenrative type, and is diode clamped.
So its output swings would be clamped, instead of going all the way toward power/ground.
The Gain-bandwidth product can be analyzed (specifically for this comparator).
Simply use balanced inputs, assign Vin(+) with ac=+.05, Vin(-) with ac=-0.5 and conduct .ac analysis.
Please feel free to comment in case you have better ideas.  |
