  1. Experiences as a Self-Motivated Researcher Dr T S Rathore, F IETE, F IE, M ISTE Department of Electrical Engineering Indian Institute of Technology, Bombay Powai, Mumbai 400 076 email: tsrathor@ee.iitb.ac.in Website: www.ee.iitb.ac.in\~tsrathor

  2. Requirements for doing research • Zeal– Where there is will there is a way • 2. Regular reading of research journals • - Library habit • - Membership of Professional bodies • 3. Topic of research • - Scan a few issues • - Papers of interest • - In-depth studies of the papers • - Literature survey

  3. Learning • - Copying – A child is the father of the man • - Chess Player • - Copying + Originality • Practice • Practice makes a man perfect • Read several times • Close the book after reading • Practicing • Write the abstract / summary • Do derivations • Solve some problems • Creative thinking • Can you rewrite the chapter • Can you think of alternative approach / derivation • Can you add a problem • Can you write a chapter for a book

  4. Don’t confine to the Book Material • Read current research papers • Don’t go for research in outdated areas but do read them and get ideas.

  5. Ask Questions? • - Why this way? • - Why this assumption? • Its effect on the result.

  6. Reading a few initial pages of the book, you should predict logically what is next in your opinion by stretching your imagination. Z, Y parameters.

  7. Network transformation • Complementary transformation • Inverse transformation • oE • 6 different functions

  8. Network transformations by switching Inv. Amplifier Non-inv. Amplifier

  9. Inv. Integrator Inv. Differentiator

  10. Papers published: • An active network transformation, IETE(I) J of Research, 1978. • 2. Inverse complementary network theorem, IEEE Proc., 1978 • 3. Generation of transfer function realizations employing inverse active network theorem, IETE(I) J of Research, 1978. • 4. Network transformations, IEEE Trans. Circuits & Syst., 1980. • 5. Complementary networks and their applications in filter design, IETE Annual Convention, 1980. • 6. Active complementary networks, IETE(I) J of Research, 1980. • 7. Active complementary networks, IEEE Trans. Circuits & Syst., 1980.

  11. RDS circuit 2n states. Whereas maximum possible states are 2nonly. Is it not possible in the beginning to find what states exist and in which order. We developed a procedure such that it automatically gives what will be the next state.

  12. Assumed Diode Method

  13. Break Point Method

  14. Sequential Break Point Method

  15. Case I – L and R complementary

  16. Case II – L and R Non-complementary

  17. DACs – Why two types only • - Optimize the spread and minimum • total resistance. • Types of DACs • - Weighted Resistor • - R - 2R Ladder • Why not more types? • Why not multistages?

  18. THANK YOU
