SEMICONDUCTOR DEVICES AND MODELLING LAB
Introduction
Semiconductor devices are the fundamental components of modern electronic circuits and systems, widely used for applications such as amplification, switching, signal processing, and power regulation. Understanding the characteristics and operation of devices like PN junction diodes, Zener diodes, bipolar junction transistors (BJTs), and metal–oxide–semiconductor field-effect transistors (MOSFETs) is essential for students of Electronics and Communication Engineering. The Semiconductor Devices and Modeling Laboratory provides practical exposure to the behavior of these devices through circuit simulation using tools such as LTspice. Simulation-based experiments allow students to analyze device characteristics under different operating conditions, study important phenomena such as temperature effects, Early effect, and channel length modulation, and compare theoretical concepts with simulated results. Through these experiments, students develop a deeper understanding of semiconductor device physics, device modeling, and electronic circuit analysis, which are essential for advanced studies and practical applications in analog electronics and VLSI design.
