Current to voltage conterter and voltage to current converter

In summary, the conversation is about creating a voltage to current converter circuit and a current to voltage converter circuit for a vibration measurement device. The speaker is unsure of how to create these circuits and asks if anyone has an example. They also mention using opamps and request assistance with determining the power supply rails and output characteristics of their 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?
 

What is a current to voltage converter?

A current to voltage converter is a device that converts a current signal into a proportional voltage signal. This conversion is achieved using a resistor and an operational amplifier.

What is a voltage to current converter?
