SUMMARY

The discussion focuses on designing an amplifier using BJTs or MOSFETs to achieve specific performance metrics: an overall voltage gain of 800, an input impedance of 200Kohms, an output impedance of 200 ohms, and a frequency bandwidth of 10MHz. Participants emphasize the importance of understanding the characteristics of BJTs and MOSFETs to meet these requirements effectively. The conversation also highlights the necessity for users to demonstrate prior knowledge and effort in their inquiries.

PREREQUISITES
  • Understanding of BJT and MOSFET characteristics
  • Knowledge of amplifier design principles
  • Familiarity with impedance matching techniques
  • Basic concepts of frequency response in amplifiers
NEXT STEPS
  • Research BJT and MOSFET amplifier configurations for high input impedance
  • Study techniques for achieving high voltage gain in amplifier circuits
  • Learn about impedance matching for optimal signal transfer
  • Explore frequency response analysis for amplifiers operating at 10MHz
USEFUL FOR

Electrical engineering students, amplifier designers, and hobbyists interested in high-performance amplifier design using BJTs and MOSFETs.

Hey, I need to design an amplifier using either BJTs or MOSFETS (or both) that meets the following requirements:
Overall voltage gain: 800

Input impedance : 200Kohms

Output impedance: 200 ohms

Frequency band width: 10MHZ

Can anyone help me with what kind of arrangement of amps can possibly achieve those requirements?

Thanks!

Welcome to PF, AC23. This is a great place. Keep in mind that homework problems should be posted in the homework forums, and you need to show some of your own work in order to get us to help. We don't do your homework for you.

That having been said, what is your background? Is this for a 1st or 2nd year intro EE class? What have you learned so far in this class that you can use for this project? Would you think that a BJT or a MOSFET would be a better choice for the 200kOhm input impedance requirement?
