Integrated Circuits and its Applications


This laboratory introduces the student to get familiarize with the basic concepts of Op-Amp. Practical demonstration of the theoretical concepts done in classrooms will enhance the understanding of the students. The experiments included in the curriculum cover majority of the applications of Op-Amp like  Op-Amp as adder, subtractor, integrator, differentiator, inverting, non–inverting amplifier, filter, oscillator etc.Few experiments based on Orcad/Virtual Lab are also included. These software based experiments allow students to view simulation results after changing different parameters of circuit. Students  can also compare the simulation results with results obtained when performed on real hardware.

The laboratory is well equipped with CRO-Cathode Ray Oscilloscope (for measuring AC and DC waveforms, amplitude, time period etc), DM-Digital Multimeter (for measuring AC and DC current and voltages), FG-Function Generator ( for generating different type of waveforms of different amplitude and frequencies), DC voltage supply of different amplitude and Bread-Board (for making electronic circuits temporarily for performing experiments).
