PROGRAMME: M.Sc. PHYSICS
The course covers theory and characteristic study of practical operational amplifiers and their general linear applications with design. Review of active filters, oscillators, comparators and converters.
The aim of this course is to introduce the students to the advanced concepts of electronics. The primary objective of this course is to understand and implement the advanced electronic circuits such as amplifiers etc with the help of theoretical and practical problem solving.
It is required from the students to understand the analog electronic circuit which in turn are used as the building blocks of the larger and more complex systems.
After studying this course , students should be able to –
1. Demonstrate knowledge of analog electrical devices, particularly operational amplifiers and their applications.
2. Derive and determine various performance based parameters and their significance for operational amplifiers.
3. Recognize different filters, oscillators, comparators and converter circuits.
Unit I - The Practical Op-amp
Input offset voltage –Input bias current – input offset current – Total output offset voltage- Thermal drift.- Effect of variation in power supply voltage on offset voltage – Change in input offset voltage and input offset current with time - Noise – Common mode configuration and CMRR.Frequency response –Compensating networks – Frequency response of internally compensated and non-compensated op-amps – High frequency op- amp equivalent circuit.- Open loop gain as a function of frequency – Closed loop frequency response – Circuit stability - slew rate.
Unit II - General Linear Applications(with design)
DC and AC amplifiers – AC amplifier with single supply voltage – Peaking amplifier – Summing, Scaling, averaging amplifiers.- Instrumentation amplifier using transducer bridge. Differential input and differential output amplifier – Low voltage DC and AC voltmeter. - Voltage to current converter with grounded load– Current to voltage converter. - Very high input impedance circuit – integrator and differentiator
