Why do we cascade amplifiers, Electrical Engineering

Assignment Help:

Q. Why do we cascade amplifiers? Why is RC coupling the most widely used coupling between 2 stages of a cascading amplifier?

The voltage or power gain or frequency response obtainable from a single stage amplifier is usually not sufficient to meet the needs of either a composite electronic circuit or load device, so cascading of amplifiers is required to provide greater voltage of current amplification of both. RC coupling is the most widely used coupling between the two stages of a cascaded or multi stage amplifier because it is cheaper in cost, it is a very compact circuit and provides excellent frequency response.
