GATE EDC QUESTION TOPICS AND PSU

              EDC  is one of the most important topics in GATE and there will be a number of question from 1 mark to 2 marks to linked answer type questions. EDC is vast topic and if prepared covers from basic to the large circuits.The following are the areas from which EDC question comes in most of the GATE and PSU. The most scoring subject for an ece student is EDC

1. Doping questions like calculation of the doping concentration, doping ratio.
2. calculation of the depletion width, electric field, mobility and basic circuits realted to Diodes
3. NPN, PNP circuits mainly their biasing and current calculations and all important circuits objectives and their formulae CE, CB and CC configurations. -- Linked answer questions
4. FET realted questions mainly deals the same topics as BJT but are not in the same quantity as BJT.
5. Various types of diodes and their equations.
6. Silicon controlled rectifier( Less in Gate)
7. Difference among quantities such as direct and indirect bandgap, avalance and zener breakdown etc.. ( Objective part) Engineering services.
8. Questions on formation of bands and their theory. Objective part both in PSU and GATE, ESE.
9. Do not ever leave the topics of BIPOLAR JUNCTION TRANSISTOR.
10. Known standard values like mobility of hole and electron, their charge etc....

All the best to GATE aspirants.
