How Do You Use Feedback in Operational Amplifiers for Signal Processing?

Click For Summary
SUMMARY

This discussion addresses the use of feedback in operational amplifiers (op-amps) for signal processing, specifically focusing on achieving a tenfold amplification of input signals through both inverting and non-inverting configurations. The user seeks guidance on implementing feedback to achieve integration over time (dt) and amplification. A reference document from Texas Instruments, "sloa058.pdf," is suggested as a resource for further understanding these concepts.

PREREQUISITES
  • Understanding of operational amplifier configurations (inverting and non-inverting)
  • Knowledge of feedback mechanisms in electronic circuits
  • Familiarity with signal processing concepts
  • Basic skills in circuit design and analysis
NEXT STEPS
  • Study the Texas Instruments document "sloa058.pdf" for detailed examples of op-amp feedback applications
  • Learn about designing inverting and non-inverting amplifiers for specific gain settings
  • Research integration techniques using operational amplifiers
  • Explore simulation tools like LTspice to model op-amp circuits and feedback behavior
USEFUL FOR

Electronics students, circuit designers, and engineers interested in signal processing and operational amplifier applications will benefit from this discussion.

>Hii everybody
Am having some problems and facing some dificulties concerning, the topic of operational amplifiers.
More precisly:
- feeding back with the inverting and non inverting terminlas, to get a ten times amplification for my input signal(DC coupled).
- feed back to get an integral over dt.
- feed back to get 10 times amplification.


i mean i did not find any good script that talk about these topics for the OP-amps.

May someone help me

i ll be so thankfull
