EI25C03 Analog Electronics Syllabus – Anna University UG Syllabus Regulation 2025

Course Objective:

This course aims to provide a solid understanding of the structure, operation, and applications of electronic devices. It focuses on biasing of BJT and JFET devices, amplifier configurations, feedback concepts, and oscillator design for specified frequencies.

PN Junction Devices

PN junction diode – structure, operation and V-I characteristics, transition and diffusion capacitances – rectifiers – half wave and full wave rectifier with capacitor filter. Zener diode – reverse characteristics – Zener as voltage regulator. Display devices – LED, Laser diode, Photodiode.

BJT and Small Signal Amplifiers

BJT – structure, operation of NPN and PNP transistor, input and output characteristics of CE, CB and CC configurations. DC Load Line and operating point, need for biasing – bias stabilization – fixed and voltage divider biasing. Single stage BJT amplifiers – AC analysis of CE and CC amplifier with voltage divider bias using h-parameters – gain and frequency response.

Field Effect Transistors and Thyristors

JFET, MOSFET – structure, operation and characteristics, JFET biasing – self and voltage divider biasing. FET small signal model – analysis of CS, CG and source follower.

Differential Amplifiers and Large Signal Amplifiers

Cascade amplifier, BJT differential amplifier – DC and AC analysis of common mode gain, differential mode gain and CMRR. Single tuned amplifier – construction, operation and frequency response. Power amplifiers – class A, class B and class C (qualitative analysis only).

Feedback Amplifiers

Feedback concepts, feedback topologies – voltage/current, series/shunt feedback – transfer gain with feedback – effect of negative feedback on input and output resistances.

Oscillators

Conditions for oscillations, RC phase shift, Wien bridge, Hartley, Colpitts, and Crystal oscillators.
