EE25C05:
Electronic Devices and Circuits
Course Objective:
The
course introduces students to the physical principles and operational
characteristics of electronic devices such as diodes, BJTs, and FETs. Through
laboratory-integrated lectures, students will apply these concepts in designing
and analyzing rectifiers, amplifiers, and switching circuits. The course
emphasizes problem-solving and hands-on skills needed for analog circuit
implementation.
Semiconductor
Physics and Diodes: Energy bands, carrier generation
and recombination, drift and diffusion currents. PN junction operation, ideal
and real diode characteristics. Diode Applications: Rectifiers, clippers,
clampers, and voltage regulators.
Bipolar
Junction Transistors (BJTS): Structure and modes of
operation: Active, Cutoff, Saturation. BJT biasing techniques and stability
analysis. Small signal analysis and single-stage amplifier design.
Field
Effect Transistors (FETs): JFET and MOSFET
structures, characteristics and parameters. FET biasing methods and analog
switching applications. Common source amplifier design and multistage
configurations.
Frequency
Response and Power Amplifiers: Frequency response of
amplifiers: low, mid, and high frequency. Decibel gain, Bode plots,
gain-bandwidth trade-off.Power amplifiers: Class A, B, AB, C – operation and
efficiency.
Feedback
Amplifiers and Oscillators: Positive and negative
feedback, feedback topologies, gain enhancement. Oscillators – Colpitts,
Hartley, Crystal – design and analysis.
