Cascade Amplifier Circuit Diagram. To design complicated systems there are mainly three fundamental configurations in the cascade design. The aim of the experiment is to study the operation of cascade amplifier and obtain the frequency response and bandwidth components and equipments required.

The bias resistors for this circuit are calculated in an example problem cascode. The spice version of both a cascode amplifier and for comparison a common emitter amplifier is shown in figure above. However in cascade amplifier meant for providing high gain only ce amplifier stage are connected in cascade.

The cb common base configuration provides a good high frequency operation.

The aim of the experiment is to study the operation of cascade amplifier and obtain the frequency response and bandwidth components and equipments required. The cascode amplifier circuit using fet is shown below. The circuit diagram of cascade amplifier is shown below. Figure 2 gives the circuit of a two stage ce audio amplifier.
