|Course Title:Electronics and Electronics Lab. Description:The properties of semiconductor and fabrication of a PN diode and BJT, and their characteristics are explained. Part 2 concentrates on analog circuit and system. Method of biasing a discrete BJT or EET are given, and stability of the operating point is discussed. The small-signal model for each device is abstained and used to calculate the performance of low frequency single stage and cascaded amplifiers. The feedback concepts of AMP. OP AMP, its characteristics and applications are described.
