ELECTRONIC DEVICES Objective The objective of this experiment was to familiarize ourselves with different kinds of semiconductor electronic devices, including P-N junction diodes, light-emitting diodes (LED), Zener diodes and junction field-effect transistors (JFET). For the purpose of this lab, a rectifier circuit was built using a P-N junction diode for Part 1. Part 2 involved the use of LED’s. For Part 3, a voltage regulation circuit was built using a Zener diode to obtain and maintain a constant voltage supply. Part 4 involved the design of a constant current supply using a JFET.
