These devices are made of semiconductor materials.To understand the operation of these devices, basic knowledge of the structure of atoms and the interaction of atomic particles in the semiconductor material are necessary. The p-n junction formed by adjacent p and n semiconductors is the basis of the operation of the diodes and transistors. This course discusses on the current flow across the p-n junction that contributes to the characteristics of the diodes, BJTs and FETs. Consequently, the characteristics of these devices determine the performance of the electronic circuits. The FETs covered in this course are the JFET, D-MOSFET and E-MOSFET. COURSE OBJECTIVES

To give understanding on how current flows through the p-n junction and relating this phenomena to the characteristics and operation of the diodes, bipolar and field-effect transistors.

To expose students to the function and application of the diodes, bipolar junction and field effect transistors in electronic circuits.
