there are so many circuits... i am confused wat to study and wat not to ?
any advice on op amp?... am refering roy choudhary "linear integrated circuits"..

any advice on op amp?... am refering roy choudhary "linear integrated circuits".. Added after 34 minutes:
is newbie tortured on edaboard or wat?
Your question is not easy to answer. Nevertheless, here are some poits I consider as important.
1.) Understand the function and the properties of a simple differential amplifier
2.) Modify this amplifier by using two supplies with the aim to allow a bias voltage at the inputs of zero volts.
3.) Realize, that an opamp is nothing else than a "very good" and specialized differential amp with a very high gain Ao and a low output impedance with a dc output voltage of zero.
4.) Understand the role of "unbalance" (mismatching of components) which leads to the definition of the OFFSET voltage.
5.) Use feedack theory to understand why the problem of offset is minimized by applying negative feedback to the opamp.
6.) Calculate the output voltage and the gain of the opamp with feedback by applying the superposition theorem or the KCL rules.
7.) Realize the simplification in the gain formula by letting Ao (open loop gain) approach infinite.
8.) If you have understood every point, you will be able to understand nearly all other application circuits.
