Detailed Solution
Download Solution PDFCascode amplifier:
- It is a cascading of Common Emitter configuration and Common Base configuration in series (CE-CB)
- It is used as a high frequency and radio frequency amplifier.
- In this amplifier, Miller's effect is negligible, which is the reason behind the increase in bandwidth.
- It is used as a Wide-band amplifier (Amplifier with large bandwidth)
- It is also available in FET as a cascading of Common source and Common Gate Amplifier (CS-CG)
