Current to voltage conterter and voltage to current converter

Click For Summary
SUMMARY

The discussion centers on creating voltage to current and current to voltage converter circuits, specifically for vibration measurement applications. Participants suggest using operational amplifiers (opamps) for circuit design, emphasizing the importance of understanding the output voltage range and impedance of the sensor. Resistors are highlighted as fundamental components in both types of converters. The conversation seeks practical circuit examples and guidance on implementation.

PREREQUISITES
  • Understanding of operational amplifiers (opamps)
  • Basic knowledge of resistor functions in circuits
  • Familiarity with voltage and current conversion principles
  • Knowledge of sensor output characteristics, including impedance
NEXT STEPS
  • Research opamp circuit design for voltage to current conversion
  • Explore resistor configurations for current to voltage conversion
  • Learn about sensor output impedance and its impact on circuit design
  • Investigate practical applications of converters in vibration measurement
USEFUL FOR

Electronics engineers, circuit designers, and students involved in sensor technology and measurement systems will benefit from this discussion.

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?
