Kahya, Associate Professor of Electrical Engineering   Goals: This course aims to expose the students to the general principles of design and applications using analog integrated circuits.   Learning Objectives: At the end of this course, students will be able to: Explain and design basic nonlinear applications such as voltage comparators, Schmitt triggers, precision rectifiers, peak detectors, track-and-hold amplifiers Design and explain signal generators including Wien-bridge and quadrature oscillators, multivibrators, timers, function generators and V-F and F-V converters Design first and second order active filters using KRC, multiple-feedback, state and biquad configurations. Compare different data conversion techniques both from analog to digital form and digital to analog form Design a data acquisition system. Design and explain log/antilog amplifiers and analog multipliers Textbook: Sergio Franco, Design with Operational Amplifiers and Analog Integrated Circuits, 3rd ed., McGraw-Hill Book Company, 2002   Prerequisites by Topic: Basic Electronics Frequency-domain analysis techniques Multi-stage amplifiers and their frequency response Basic skills in PSpice Topics: Nonlinear Circuit Applications ( 11 Lecture Hours ) Voltage Comparators and Applications Schmitt Triggers and Applications Precision Rectifiers Analog Switches Peak Detectors Sample-and-Hold Circuits Signal Generators ( 10 Lecture Hours ) Sine Wave Generators Multivibrators IC Timers Triangular Wave Generators Triangular-to-Sine Wave Converters Sawtooth Wave Generators V/F and F/V Converters D-A and A-D Converters ( 12 Lecture Hours ) Converter Definitions and Specifications Basic DAC Techniques Bipolar DAC's High-Resolution DAC's DAC-Based A-D Conversion Parallel A-D Techniques Integrating-Type ADCs Oversampling Converters Logarithmic Amplifiers ( 6 Lecture Hours ) Log/Antilog Amplifiers Analog Multipliers Course Structure: The class meets for three lectures a week, each consisting of 50-minute sessions. 4-5 sets of homework problems are assigned per semester.  There are two in-class mid-term exams and a final exam. There is one hardware project consisting of circuit design and implementation.   Computer Resources: Students are encouraged to use PSpice to solve their homework problems.   Laboratory Resources: The hardware project is carried out in the electronics laboratory.   Grading: Two Midterms (20% each) Final (35%) Weekly Homework Assignments and Quizzes (10%) Term Project (15%) Outcome Coverage: Apply math, science and engineering knowledge.This course is about general analog circuit principles and applications using analog integrated circuits.Different tools from mathematics (differential equations, complex variables) in frequency domain analysis as well as from sciences (physics) in measurement circuits and engineering (electronics) in circuit analysis and design are heavily drawn upon during lectures, homework sets, exams and laboratory assignments. Design a system, component or process to meet desired needs. Designing analog circuits for different applications account for more than half of the course time. The design approach is further reinforced in a laboratory assignment which involves a system which samples the temperature at 10 Hz with 8-bit resolution and monitors it on display and whenever the temperature is outside a predefined range, drives a relay. All the blocks are built using the course material: Schmitt trigger, multi-vibrator, filter, ADC, etc. Ability to communicate effectively. Students are required to write a laboratory report on their design assignments and part of the grade is based on the writing style, technical content and presentation quality, both written and oral. Use of modern engineering tools. Students use PSpice for their homework assignments. Prepared By: Yasemin P. Kahya   Last Revised: May 21, 2003
