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
 

u can achieve this with transistor using amplification
 

This is a bit of a mess. The OP has started 3 or 4 threads seemingly on the same topic. I answered one of the others here earlier.

Apparently he wants to boost the output of an AD620 opamp to drive a current of up to 200mA into a load of 500Ω (or 120mA into 1k, pick your thread).

Not sure if his thread about boosting the current output of an AD620 to drive a 1:10 transformer is related.
 

ya...the load is 500 ohm...and it has to be grounded....max frequency is 2000Hz.. i have a 12V and -12V source......
