Emitter Coupled Cascode Amplifier Circuit Diagram. Cascode is a technique implied to improve the performance of the analog circuits. In2 to zero the dc equivalent circuit thus obtained is shown in fig below.

Capacitor coupled three stage common emitter amplifier capacitor coupled for a cascade example. Practical cascode amplifier circuit. The circuit diagram of fet operated cascode amplifier is shown as below.

At source and drain terminals q1 has fixed voltage levels whereas at gate and source terminals q2 has fixed voltage levels.

The tern cascode was used in an article which can be written by roger wayne hickman and frederick vinton hunt in the year 1939. In the circuit design of the cascode amplifier output values are completely separated from the input. The word cascode is initiated in the year 1939 by frederick vinton hunt s and roger wayne hickman s article during the discussion of voltage stabilizer applications. Capacitor coupled three stage common emitter amplifier capacitor coupled for a cascade example.
