EECE 416/501 Project 5 Due 11/12/2008 Fall 2009 Current Mirrors This project is to be completed in groups of 2. Academic Honesty Policy All students must adhere to the Student Academic Honesty Code of the University and the Watson School. The Electrical and Computer Engineering Department has adopted a standard policy to enforce these codes for course work violations. Category I violations result in a grade of 0 for the graded work plus a full letter grade reduction for the course. A Report of Category I Academic Dishonesty form is filed with the Provost's Office; if a prior report is already on file, the offense is automatically elevated to Category II. Category II violations result in at least a failing grade for the course plus any additional penalties determined by the Watson Academic Integrity Committee. Goal and General Description The purpose of this project is to compare the advantages and disadvantages of various current mirror topologies. Through simulation, the student will examine the effects cascode transistors and their biasing circuits can have on the accuracy and operating range of a current mirror. Procedure For this project, you will be simulating and comparing the current mirror topologies illustrated in Fig. 1. Figure 1. Current mirror topologies.
