Hallo Abhishek,

you can learn very much, when having a look in older databooks of Analog Devices, BurrBrown, Texas Instruments, Lineary technology, a.s.o.. There are very brilliant datasheets and application notes, which unfortunately are removed to a great amount from today databooks. So, if you can put your hands on such an old databook, never give it away again!

Bye,
Kai
