Hi All,

I was simulating shunt-peaking amplifier and comparing this with a normal amplifier w/o inductor.

From the theory, inductive peaking increases bandwidth by serially charging the parasitic capacitance, which is direct trade b/w signal delay and the bandwidth.

However, when I simulate the circuit, I DO NOT SEE any delay from the inductor.
Is this normal ?
