This document contains a lecture plan for a course on Electronics Devices and Circuits. It is divided into 5 units covering various electronic components and circuits. The plan lists the topics and sub-topics to be covered in each unit along with the corresponding lecture day and mode of instruction. Some of the key topics included are semiconductor diodes, rectifiers, bipolar junction transistors, field effect transistors, thyristors, amplifiers and oscillators. For each unit, lectures are allocated for teaching concepts, discussing questions, and conducting student seminars and tests. The overall aim is to provide a comprehensive overview of electronics devices and circuits across 60 lectures.
