op linearity

Dear all:
In OP design , how can I improve opamp linearity?

ps: OP can be any type, so don't care op type.
please focus on opamp external circuit method.

thanks.

Negitive feedback can improve the linearity. Pre-distotion can do the same work but has some complexity.

use source negetive feedback to reduce the gain.
