I took this subject for teaching because of unavailability of teachers. In October 2016, new teacher took this responsibility. So, this course is over.

### Unit I

**Four terminal network:** Ampere-volt conventions, open, close and hybrid parameters of any four terminal network; Input, Output and mutual impedence for an active four terminal network.

**Various circuit theorems:** Superposition, Thevenin, Norton, reciprocity, compensation, maximum power transfer and Miller theorems. **PN junction:** Charge densities in N and P materials; Conduction by drift and diffusion of charge carriers, PN diode equation; capacitance effects.

### Unit II

**Rectifiers:** Half-wave, full wave and bridge rectifier: calculation of ripple factor, efficiency and regulation; Filters: series inductor, shunt capacitor, L section and π section filters.

**Voltage regulation:** Voltage regulation and voltage stabilization by Zener diode, voltage multiplier.**Transistors:** Notations and volt-ampere characteristics for bipolar junctions transistor; Concept of load line and operating point, Hybrid parameters. CB, CE, CC configurations; Junction field effect transistor (JFET) and metal oxide semiconductor field effect transistor (MOSFET), Circuit symbols, biasing and volt-ampere characteristics, source follower operation of FET as variable voltage resister.

### Unit III

**Transistor biasing:** Need of bias and stability of Q point, stability factors and various types of bias circuits for thermal bias stability: fixed bias, collector to base feed back bias and four resistor bias.**Amplifiers:** Analysis of transistor amplifiers using hybrid parameters and its gain-frequency response; Cascade amplifiers, basic idea of direct coupled and R-C coupled amplifiers; Differential amplifiers.
