Introduction for Semiconductor Devices Modeling and Technology Laboratory

 

Semiconductor Devices Modeling and Technology lab mainly emphasis on building a bridge between theoretical knowledge gained during lecture sessions and its implementation in the practical world.

The purpose of conducting experiments can be stated as follows:

  • To get familiarization with the basic components, devices, modules, etc. used for constructing circuits.
  • Circuit drawing using standard symbols as practiced in network technology
  • Making proper connection in the modules as per the circuit diagram and connection of appropriate power supply for energizing the circuits.
  • Conducting experiments as per the guidelines and writing of results of observation.
  • Verification of theoretical results through graphs or calculations
