how can i realize this ?

input voltage is 0.2~4V,divided into two ways,A and B.when input is 0.2~2V,voltage of A way is 0.05~0.95V,voltage of B way <0.05V;when input is 2~4V,voltage of A way is 0.95V,voltage of B way is 0.05~0.95V.how can i realize it ?

Hmmm, looks like a homework question. I don't do homework because you don't learn anything.

What is your *OWN* conclusion to your question sofar?
