Using op-amps, which have a gain x bandwidth constant

Click For Summary

Discussion Overview

The discussion revolves around designing circuits using operational amplifiers (op-amps) with a specified gain x bandwidth constant. Participants are tasked with creating an inverting amplifier, a differential amplifier, and a current to voltage converter, while also seeking guidance on the methodology for these designs.

Discussion Character

  • Homework-related
  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant requests assistance in designing three specific op-amp circuits, detailing the required specifications for each circuit.
  • Another participant points out that the requested circuits are basic and provides links to external resources for reference.
  • A subsequent reply asks for a worked example to better understand the design method.
  • Another participant emphasizes that the forum expects users to engage in the work themselves to receive help.

Areas of Agreement / Disagreement

Participants do not appear to reach a consensus on the approach to take for the circuit designs, with some advocating for self-driven effort while others seek direct assistance.

Contextual Notes

The discussion reflects varying levels of familiarity with op-amp circuit design, and there are references to external resources that may not be universally accessible or applicable to all participants.

Who May Find This Useful

This discussion may be useful for students or individuals seeking to understand basic op-amp circuit design and the expectations of collaborative problem-solving in a forum setting.

Using op-amps, which have a gain x bandwidth constant of 500,000, design the following circuits. Include circuit diagrams, the appropriate theory and details of how you calculated the values of all the components used.(i) An inverting amplifier with a gain of 500, having an input impedance of 20kΩ.

(ii) A differential amplifier, which amplifies the voltage difference between two signals, V1 and V2, by a factor of -10

(iii) A current to voltage converter, capable of converting 100mA into 1V.

I have no idea how to work this out, please help. thank you.

could you do one for me then i will understand the method thanks
 
That is not how the PF works. YOU do the work, or we can't help you.
