Electronics is that branch of Physics which basically deals with the characteristics and behavior of the carriers - electrons and holes and their interactions in several semiconducting medium. Thus the information specially about semiconducting electronics is the main objective of this course. Here we discuss basic analog part of electronics phenomena and the discussion is then carried out to the advance level step by step. We discuss basic nature of semiconductor and gives a clear idea about pure and impure semiconductors and their application to p-n junction diodes and junction transistor (BJT) along with their applications. Diodes as rectifier in power supply and also application of diode in voltage stabilizer in electronics are also discussed carefully in respect of both theoretical analysis and practical applications. The behavior and characteristics of transistor and its application in broad sense is discussed here and the discussion is extended to transistor biasing along with the principle of JFET, MOSFET and Thyrister which is commonly known as Silicon Controlled Rectifier. Also idea about Feedback Amplifier and Operational Amplifier (OPAMP) including several application of OPAMP are discussed in this course in details. Another essential part of electronics is modulation and demodulation which is an essential part of communication. Here mathematical analysis of modulation and demodulation and principle of several modulator and detector are also discussed at standard level with easy mathematical analysis. I think that the students of science at basic and advanced stage, both will be highly benefited by this course and it will be helpful for their subject preparation.
