The defintion of folded cascode.
From the picture seems like the definition of cascode is
1)
1)The input tansistor turns from nmos to pmos. or if differential, turns both nmos to pmos.
2)insert a current source between the input transistor and the upper load transistor.
The objective is improve the output swing and input swing.
Is that good enough observation for folded cascode?
but turning the input transistor from nmos to pmos, that would make circuit slower? No?
