input impedance, output impedance, gain, pole, zero calculation from inspection

[mdmIC]

how can the following parameters of any MOSFET amplifier circuit can be calculated just by inspection?
-input impedance
-output impedance
-gain
-pole
-zero
please give reference of webpage and/or books so that i can study further

You can calculate those spec's by inspecting its schematic or its circuit.
You must learn the basics of electronics to calculate them and you must have some experience by inspecting just the circuit without a schematic.
