can u suggest any current booster IC or current amplifier circuit to convert 1-10mA to 1-200mA.......the signal has i/p voltage of 10

 

More detail?
accuracy?
speed? (bandwidth)
sourcing or sinking?

 

What load resistance?
Is this a controlled constant-current source?

 

500 ohms load......no it's not a controlled current source.........
