MOSFET

If you are clear about the analysis of BJT then understanding MOSFET should be a cakewalk. You have to start from the same point where you started BJT from that is the basics of the device and the current-voltage equation. Then based on characteristics of the device you have to understand the different operating regions of MOSFET which are cut-off, Linear and Saturation. Then you can move onto the biasing techniques of MOSFET which are identical to BJT but the main difference is that Gate current is zero due to insulator between gate and device.

After the biasing you can study about the small-signal model of the device and the best part is that there is only one model that you have to study which is the Hybrid-pi model and you have to understand the amplifier analysis using this model. Also, you must know how to derive certain parameters like Trans-conductance and Output Resistance using DC Analysis. Again you will derive the same parameters as in BJT which are Voltage Gain, Input resistance and Output Resistance for various configurations such as Common Source Amplifier with and without bypass capacitor, Common Drain, and Common Gate Amplifier. Again you have to study about the frequency response of the amplifier and derive the cut-off frequency but once you understand the basic method this won’t be a problem for you if you are able to draw the small-signal model. Then the last part involves multi-stage amplifier i.e. Cascade and Cascode Amplifier.
