The cascade amplifier is a multistage configuration of

Solution (By Examveda Team)

Explanation of each option:

Option A: CC-CB is incorrect because this configuration consists of a common collector (CC) stage followed by a common base (CB) stage. While this can be used in some amplifiers, it is not a typical configuration for a cascade amplifier.

Option B: CE-CB is incorrect because this configuration consists of a common emitter (CE) stage followed by a common base (CB) stage. While this may be used in certain applications, it is not the standard configuration for a cascade amplifier.

Option C: CB-CC is incorrect because this configuration starts with a common base (CB) stage followed by a common collector (CC) stage. This is also not a common arrangement for cascade amplifiers.

Option D: CE-CC is correct because the typical cascade amplifier configuration uses a common emitter (CE) stage followed by a common collector (CC) stage. The CE stage provides high voltage gain, while the CC stage provides current gain and impedance matching, making this a common choice for multistage amplifiers.

Conclusion: The correct answer is Option D: CE-CC because this is the standard multistage configuration for cascade amplifiers.
