What configuration should be created to simulate output/input swing of a amp?
It is differential input and differential output folded cascode amp.
Thx!
Hi.
I think, .Tran analysis should be used for output swing calculation. you can use a .measure statement to measure p-p swing. e.g.
.meas tran swing PP v(out) from=0.1ms to=0.2ms
where in this case 0.1ms is the period of input voltage.
But don't forget, you must calculate THD at least by using .four statement. having THD more than 2 or 3% is not very suitable in any application.
