A simple direct coupled inverting amplifier can be realized using only two external resistors; R'_IN_' which defines the input resistance and R'_F_' which defines the closed-loop voltage gain. Thus:

Input resistance = R'_IN_'

and

Voltage gain, A'_V_' = R'_F_'/R'_IN_' (:nl:)(:table style="clear:both":)
