I need help in designing an opamp circuit with the following features:

A difference of 45.9mV for the Vin will result in a 0.1V difference for the Vout.

For example, if Vin=4.1V and Vout =5V
a change in Vin = 4.05V will make Vout = 4.9V

It doesn't matter what are the values of Vin and Vout, it's the difference that's important.
