Analog Circuits laboratory(18ECL48) is one of the major laboratory courses for Undergraduate students of Electronics and Communication Engineering. The laboratory experiments in this course can be broadly classified as firstly hardware experiments conduction under Part A which includes study of amplifiers, filters and signal converters. Secondly simulation of these electronic circuits as Part-B. Analog Electronics as the name suggests deals mainly with the processing of Analog signals. Analog electronic circuit design is one of the important and challenging field in Electronics. It is also one of the vast and complex areas in VLSI circuits design. A signal which is having different values at different instants of time and having its value defined at every instants of time is referred to as an analog signal. Circuits to process analog signals are necessary because all the naturally available signals like human speech, sound, biomedical, temperature etc are analog in nature. Many analog circuits are available in the form of IC chips. During this Lab course simple analog electronic circuits are designed using discrete components like Resistors, Capacitors, Inductors, PN junction diodes and Transistors (BJT’s, FET’s, etc.). These designed circuits are tested and verified for their performance under the laboratory conditions using power sources like DC Power supply, AC sources like function generators. Their input and output parameters like input waveforms, output waveforms, input and output current and voltage readings, the impedance or resistance offered by the circuit, etc are analyzed by using measuring instruments like multi-meter and CRO’s. The captured values from the instruments are noted and used for further calculations.
This laboratory course completely deals with basics of analog electronic circuit design and their experimental observations. Here the students are exposed to design and implement the analog circuits like Amplifiers using FET’s and BJT’s, oscillators such as Colpitt’s and Crystal oscillators, active low pass and high pass filters, Adder, Integrator and Differentiator circuits using Op-Amp, Schmitt trigger and digital to Analog, Analog to Digital converters etc.. For all these experiments, the input and generated output waveforms are sketched and the results are noted for further calculations. Analog electronic circuits such as Narrow Band Pass and Band Elimination filters, RC and Hartley oscillators, Precision Rectifiers and Multi-vibrators are designed and tested for their performance using the CAD tools like PSPICE.
