Cascode Amplifier using MOSFET Explained (Cascode Amplifier with Cascode Current Source)

In this video, what is Cascode Amplifier, and the small-signal analysis of the Cascode Amplifier is explained in detail. Using the small-signal analysis, the expression of output impedance and the intrinsic gain of the Cascode Amplifier is found. At the later part of the video, the effect of load on the voltage gain of the cascode amplifier is explained by taking the example of the passive-resistive load, the active PMOS current source as a load, and the cascode current source as a load.

The Cascode Amplifier is the combination of the Common Source and the Common gate stages. In this configuration, the input is applied to the Common Source Stage and the output of the Common Source Stage is fed to the Common Gate stage. The Cascode Amplifier provides 1) High Input Impedance 2) High Output Impedance 3) High Intrinsic Gain 4) Large Bandwidth In this video, through a small-signal analysis, the equation of the output resistance and the Intrinsic gain of the cascode amplifier is derived. And the effect of various loads on the voltage gain of the cascode amplifier is discussed....
