What are the advantages of two stage op amp?

The advantages of two stage op-amp have good gain, high output swing, low noise and good bandwidth over folded cascode. And it needs compensation, low PSRR value compared to folded cascode.

What are the advantages of RC Coupled amplifier?

Advantages of RC Coupled Amplifier

  • The frequency response of RC amplifier provides constant gain over a wide frequency range, hence most suitable for audio applications.
  • The circuit is simple and has lower cost because it employs resistors and capacitors which are cheap.

What is the application of two stage RC Coupled amplifier?

Applications of RC Coupled Amplifier RF Communications. Optical Fiber Communications. Public address systems as pre-amplifiers. Controllers.

What is the need for two stage amplifier?

Two-stage operational amplifiers are the most common used multistage amplifier because it can provide high gain and high output swing. However, an uncompensated two-stage operational amplifier has a two-pole transfer function, and these are located below the unity gain frequency.

What is the advantage of RC coupled amplifier Mcq?

Explanation: RC coupled amplifiers have low voltage and power gain. It is because the low resistance presented by the input of each stage to the preceding stage decreases the effective load resistance and hence the gain. Thus its efficiency is reduced.

How do you increase the gain on a two-stage amplifier?

one way is simply increase the gm of the first stage input transistors pair, by enlarge the W/L ratio, not by adding the bias current. and the second stage input transistor also.

What is 2 stage amp gain voltage?

5.8a (and which becomes the input voltage to the second stage) and A1 and A2 are the gains of the first stage and second stage, respectively. Hence the overall gain of the two-stage amplifier is A = A1A2 or simply the product of the gains of the individual stages.
