Is there anyone that can help me build an AB amplifier with the characteristics attached to these in LTspice, at least the schematic circuit. Thanks...
 
We don't do homework for you. You need to show what you've done so far.
 
Hi Thank you, the circuit is attached the one im working with and the other is a screenshot of what I wanted to do exactly but I think there is wiring wrong.
This is a source cross-coupled amplifier; 100pF load need to connect to find the gain but the problem is the W/L need to adjust such a way that the quiescent current is IDD|opamp less than or equal to 500 mA

Sorry, I'm not familiar enough with IC design to help you with that. You might try posting here.
