Start date: June 18, 2024 End date : June 29, 2024
Mid Evaluation date : June 24, 2024 End Evaluation Date : June 29, 2024
Total number of participants : 64
Name of the Instructor : Prof Anil Kottantharayil, IIT Bombay
Venue and Location: Wadhwani Electronics Laboratory <https://www.ee.iitb.ac.in/~wel_iitb/index.php>
Mode of Workshop : In - person at IIT Bombay
Basic qualification for the participants expected:
Third-year students pursuing B.Tech./B.E. in Electronics Engineering or M.Sc. (Electronics/ Physics with basic Electronics background) or equivalent program with a good background of basic Electronics, Analog circuits.
Entry criteria for participants:
Courses which the student should have studied:
- Basic Electronics, Analog circuits or linear integrated circuits (mandatory)
- Basic knowledge of NgSpice or LTSpice simulation software (preferred)
- Any relevant courses passed through NPTEL with good grades.
Attending an online test/exam to see if they have pre-requisites or maybe an SOP:
- No online test/ exam (first-come-first-select basis): Should fulfill the criteria of pre-requisites and basic qualification.
Workshop Fees: Rs. 1000 (Registration fee - Rs. 200 + Caution deposit amount - Rs. 800). On successfully completing the workshop Rs. 800 will be refunded.
Note: Caution Deposit amount of Rs. 800 will not be refunded if the participant does not complete the workshop or is absent during the workshop
List of experiments to be covered:
1) Understanding lab instruments: AFG, DSO, PS and DMM familiarization (non-graded exercise)
2) Op-amp Internals and OTA design:
- Differential amplifiers and current mirrors circuits
- Single-stage OTA design
- Non-idealities of op-amps
3) Instrumentation amplifier related labs:
- Instrumentation amplifier design and sensor (load cell) interfacing
- Simple OPAMP applications circuits (strain- gauge based cantilever deflection measurement)
4) Applications circuits– I: Filters and Oscillators:
- Voltage controlled oscillator
- Active filter circuits
- Narrow band filters and frequency synthesis (Fourier series) OR
5) Applications – II: Phase sensitive detection (PSD):
- Phase sensitive detection circuits, extraction of signal buried in noise
- Application of PSD: gray scale detection (how dark is dark)
OR some other concept and application theme will be taken up as a design problem.
* Each topic tutorials/ lectures and experimentation will be covered in approx. 1-2 days.
Learning Objectives:
Basic:
- Learn how to use basic electrical characterization equipment
- Learn how to analyze basic op-amp circuits and op-amp internal circuit
Intermediate:
- Predict and interpret circuit performance
- Design test setups and circuits to perform task at hand
Advanced:
- Apply concepts from other courses to the lab, and vice versa
- Absorb the underlying techniques and apply them to other circuit applications
Instructions for the lab workshop:
- Own laptop (preferred) to install the necessary software which will help to learn/ understand the concepts and implementation of the design independently.
- The supporting documents to revisit the concepts, software installation guidelines will be shared before the start of the workshop to set the base to get started on the first day.
- MS Teams link will be provided to get access to the course material and related instructions
Certificate :
Certificates will be awarded to the participants based on attendance and final exam scores
Split of marks for the workshop:
Internal: 40% (Experimentation)
Exams: Mid-evaluation exam (after week-1): 20%
Course End exam: 40%
