Current to voltage conterter and voltage to current converter

Click For Summary

Discussion Overview

The discussion revolves around the design of voltage to current and current to voltage converter circuits, specifically in the context of vibration measurement applications. Participants are exploring circuit examples and design considerations for these converters.

Discussion Character

  • Technical explanation, Conceptual clarification, Debate/contested, Homework-related

Main Points Raised

  • One participant expresses a need for examples of voltage to current and current to voltage converter circuits.
  • Another participant suggests that a resistor can function as both a current to voltage converter and a voltage to current converter, prompting a question about the context of the assignment.
  • A participant specifies that the converter is intended for use in vibration measurement, where the output is voltage, and seeks guidance on converting this voltage to current.
  • Further inquiries are made regarding the intended use of the current, the available power supply rails, and the characteristics of the sensor output, including voltage range and output impedance.

Areas of Agreement / Disagreement

There is no consensus yet, as participants are still exploring different approaches and requirements for the converter circuits.

Contextual Notes

Participants have not yet clarified specific assumptions about the circuit design, such as the choice of components (opamps vs. discrete transistors) or the detailed specifications of the vibration measurement sensor.

Well, a resistor is a current to voltage converter and a voltage to current converter. What is the context of your assignment? Do you want to use opamps, or discrete transistors, or something else? What are your thoughts so far on how to accomplish these converter circuits?

i have to make a converter which is use in vibration measurement. in vibration measurement, output is voltage, and i want to make devices that can convert voltage from vibration measurement to current. but i don't know how to make the circuits? do you have an example the circuit of that devices?
sorry my english is bad...
thanks...
 
Okay, we can probably suggest a simple opamp circuit for you. What do you want to do with the current? Will it just flow through some load to ground? What power supply rails do you have available? What is the range of the voltage that is output from your sensor, and what is it's output impedance?
