WHY CASCODE BETTER?

IT IS A SINGLE STAGE AMPLIFIER WITH GAIN ENHANCEMENT.
WHILE A CASCADE IS TWO STAGE AMPLIFIER.
IT HAS SINGLE NODE IS AT HIGHER IMPEDENCE,WHERE GAIN IS REALIZED.
IN THIS GBW IS DETERMINED BY INPUT TRANSCONDUCTANCE AND LOAD CAPACITANCE.

Automatic temperature controlled fan
Here is a scheme through which the fan can be linearly thespeed controlledautomatically, dependingon the room temperature. The scheme is effective because it ishighly control thyristors forpower. Alternatively, samecircuit can be used to automatically control AC temperaturecontrolled.In this diagram, temperature NTC thermistor is sensorused, i.e. one Havinga multiplier negative temperatures. The resistance of the thermistor in Thevalue 25 with the isabout 1 kilogram-ohm.Op Amp A1 essentially works for ASI t ....etc

Cascode amplifier
An amplifier stage consisting of a common-emitter transistor cascaded with a common-base transistor (see illustration). The common-emitter-common-base (CE-CB) transistor pair constitutes a multiple active device which essentially corresponds to a common-emitter stage with improved high-frequency performance. In monolithic integrated-circuit design the use of such active compound devices is much more economical than in discrete designs. A similar compound device is the common-collector-common-emitter ....etc
