Course Objectives

One of the main goals of this course is to explain the basic concepts of semi-conductor diode and its current-voltage relationship. Various applications of junction diode are discussed and various types of diodes are also explained. Bipolar Junction Transistors (BJTs) and Field-Effect Transistors (FETs) are evolved as two PN-junction devices. Relations of various currents and voltages in these transistors are explained in detail. The effect of temperature on these semiconductor devices is highlighted. Similarly, the working principles of Op-Amps and MOSFETS are also taught. Their critical parameters impacting design of amplifiers are talked about in detail. A variety of applications of various types of transistors, Op-Amps and MOSFETS are dealt with. The course is directly supported with lab experiments embracing the design principles.
