Laboratory	1. Performance Comparison of Common Emitter (CE), Common Base (CB), and Common Collector (CC) Amplifier Configurations at Mid-Band Frequencies 2. The BJT Differential Amplifier
Details of Assignment	Example: Titles: Performance comparison between common emitter (CE), common base (CB), and common collector (CC) amplifier Design of basic BJT current source Design of basic BJT differential amplifier Objective: To sharpen students’ design skills, which after completing the projects, students will be able to design and analyse microelectronic circuit block based on the specifications. To expose students to the design and simulation tools used by the industries in designing microelectronic circuit blocks. During the course of the design labs, students will be going through an initial design flow, from hand analysis to schematic capture and simulation. Type:Program design and implementation & Software Simulation Description: In this lab, students are asked to design and solve three different tasks given their detailed specifications. Students are then required to draw the schematics and verify the functionalities of the circuits using SPICE tools. Detailed procedures on how to design a circuit are not given in the lab sheet. Students will have to use their creativity in designing a specific circuit, taking into consideration design tradeoffs. This will also sharpen students’ design skills, as engineers are not procedure-followers. An introduction session will be held to get students acquainted to the design/CAD tools.
