I have calculated (with help) the input impedance of this common base transistor stage as 6.8 ohms. Now I want to know the output impedance of this stage.
I calculated the reactance of the inductor attached to the collector pin (assuming a value of 100 uH and a frequency of 5 mHz) as 3141 ohms. But I know from several sites that the output impedance of this type of amplifier is very high - in the megohms. So my question is: how can I calculate the output impedance for this circuit?
