In this video, we introduce Comparators using Operational Amplifiers (Op-Amps). You’ll learn what a comparator is, how an op-amp works as a comparator, and why it is widely used in electronics and instrumentation.
🔹 Topics covered in this video:
• What is a Comparator?
• Op-Amp as a Comparator
• Inverting and Non-Inverting Comparator
• Zero-Crossing Detector
• Comparator Output Characteristics
• Difference between Op-Amp and Comparator
• Practical applications of comparators
🔹 Key Applications:
✔ Zero crossing detectors
✔ Voltage level detectors
✔ Over-voltage and under-voltage protection
✔ Analog-to-digital conversion
✔ Wave shaping circuits
This lecture is very useful for undergraduate students of Physics and Electronics, especially for BSc, MSc, BTech, Diploma, and competitive exams.
📌 Watch till the end for clear concepts and easy explanations!
