Mayur, Page 323 of the ATMega128L datasheet (http://www.atmel.com/dyn/resources/prod_documents/doc2467.pdf) only gives the following data:
Icc 4Mhz Active 5.5mA Max Icc 4MHz Idle 2.5mA Max Icc Power-down mode WDT enabled <15uA Typ 25uA Max Icc Power-down mode WDT disabled <5uA Typ 10uA Max There are also graphs that show Icc Power-save WDT disabled 25oC 8.5uA Icc Standby 4MHz Xtal 80uA Icc Standby CKOPT programmed 4MHz Xtal 0.4mA Further pages show graphs for variations with voltage, clock frequency, and temperature. There is no information about ADC Noise Reduction and Extended Standby, but you might be able to guesstimate from their definitions in that same datasheet. Best to connect to an external power supply, stick a low-ohm sense resistor in the positive supply path, capture the voltage drops with a ground-isolated oscilloscope, and convert. For lower current modes, you'll be safe using a larger-ohm sense resistor.
