Cascade Amplifier Question & Answers

October 6, 2022 By WatElectronics

This article lists 50 Cascade Amplifier MCQs for engineering students. All the Cascade Amplifier Questions & Answers below include a hint and a link to the relevant topic wherever possible. This is helpful for users who are preparing for their exams, interviews, or professionals who would like to brush up on the fundamentals of Cascade Amplifier.

An amplifier consisting of one transistor fails to provide the required bandwidths. Impedance matching provided by such a circuit is poor. Several amplifying stages are combined to overcome the problem of a single transistor amplifier.

Multiple amplifiers are merged and form a single device where the bandwidth and the gain product obtained are highly stable. Higher bandwidths and gains are achieved using multi-stage amplifiers. As the stages tend to increase bandwidth increases proportionally after a certain stage it begins to decrease. This is considered to be the downfall of Cascade amplifiers.

Network of series connected amplifiers where the outcome of each amplifier fed as input to other amplifiers referred to as Cascade amplifier. Daisy chain configuration is followed in multi-stage amplifiers.

LASER pulse driving amplifiers, and RF designs containing power amplifiers are examples of Cascaded amplifiers. To build a new component architecture for desired application a custom amplifier can be cascaded. Output and inputs are highly isolated in cascaded amplifiers.
