For a non-linear device, V I ≠ d V d I (Except perhaps for some very specific values of V and I). So, we cannot use r to determine either V or I. That is why r is not used in DC analysis.

Web2. Common-Gate Amplifier: • A current buffer takes the input current which may have a relatively small Norton resistance and replicates the current at the output port, which has a high output resistance • Input signal is applied to the source • Output is taken from the drain • To first order, current gain ≈1 –is ≈-iout.(Current ...

WebFrom the small-signal model, we see that the amplifier consists of a current source and two resistors. Since the two resistors appear in parallel, we can merge them as R_o^\prime = r_o \parallel R Ro′ = ro ∥ R. Then the output voltage is simply the voltage drop across R_o^\prime Ro′.
