I have a small doubt regarding MOSFETS, recently we were working with MOSFET circuits such as tuned amplifiers and multistage amplifiers, the theoretical and practical values are very deviating, what might be the reason?
1. Component tolerance
2. Theoretical circuits like the ones in text books have limitations and they don't work straight away practically. Require some tuning before theoretical matches practical. This is why circuits are not straight forward and we perform simulation. Even after simulation, we might need lot of tuning

3. Simulate and try with different values that is where we have DC sweep kind of scenarios to find the right value
4. If not simulation, we have to try with different component values in the circuit while measuring practically. The trick to these tuning is, identify the right component in the circuit which gives the desired output and work on it
