**Description:**The transistor, which is one of the most important inventions of the 20th Century, was invented in 1947. Integrated circuits with several transistors started appearing in 1959. Ever since, electronic circuits have become smaller, cheaper, and more capable at a pace unparalleled by any other technology invented by mankind. This is exciting and inspiring on one hand, but can also be intimidating and overwhelming on the other hand for someone who wants to analyze, understand and design electronic circuits and devices.

The goal of this course is to introduce students to the components, the analysis and design methods, and the underlying principles that make up the framework for creating and implementing electronic circuits for almost any conceivable task. The main emphasis is on developing an engineering point of view that is a mix of practical experience, good intuition, and the capability to apply the mathematical laws that govern the behavior of electronic elements and circuits. Both analog and digital circuits will be covered. In the laboratory students will learn how to implement electronic circuits and how to measure their performance using multimeters, waveform generators, and oscilloscopes. Several mini-projects will be completed in the first part of the course. The final project is to design, implement, and test a digital clock.

**Concepts Covered:****Introduction:**Schematics, circuit variables, waveforms, passive/active elements, conventions, circuit topology, circuit implementation.**Basic Laws:**i-v characteristics, independent sources, Ohm's law, nonlinear elements, Kirchhoff's laws, resistors in series/parallel, voltage/current division.**Transistors:**Dependent sources, bipolar junction transistor, transistor switch, emitter follower, common emitter amplifier, field effect transistors.**Capacitors and Inductors:**Capacitor, inductor, RC circuits, RL circuits, step response, sinusoidal response, impedance and admittance.**Operational Amplifiers:**Ideal OpAmps, real OpAmps, inverting amplifier, noninverting amplifier, sum and difference amplifier, integrator, differentiator, absolute value circuit, analog computer, comparator.**Digital Logic:**Digital versus analog, number codes, Boolean logic, truth tables, TTL, CMOS, three state and open collector devices, memory, 7-segment decoder.**Sequential Logic:**Flip-flops, multivibrators, counters, shift registers, synchronous and asynchronous circuits, multiplexing.**Filters:**Time and frequency domain, lowpass filters, highpass filters, bandpass filters, filter design, Fourier series.

**Course Format:**We will frequently use the class contact time to explore and answer questions and to solve problems. For each class period two students will be assigned as note takers. The notes will be posted on the class website as reference and to document the work that was done in class. Short quizzes will be given every other week instead of midterm exams.

**Course Requirements:****Attend class**.**Note taking and class participation**(~5%)**Clicker questions**(~10%)**Homework**(~10%): Approximately weekly.**Labs**(~20%): Weekly on Fridays. You will work in groups of 3 with rotating roles within the group. A group lab report will have to be turned in on D2L for each lab.**Final Project**(~25%): Design, implementation, and test of a digital clock. This is an individual project that you will take home at the end of the semester. The time allocated for this will be approximately the last 5 weeks of the semester.**Quizzes**(~5% each): Six quizzes, closed book, closed notes. Dates: Mon. Feb. 3, Feb. 17, Mar. 3, Mar. 17, Apr. 7, Apr. 21**Final exam**according to Final Exam Schedule: Wed. May 7, 1:30 - 4:00 pm. Closed book, closed notes. There will be eight exam questions, four corresponding to one of the four quizzes given during the semester and four "joker" questions. You can replace the lowest score on each quiz by the score of the corresponding quiz problem on the final (if it is higher). The score of each joker question is used as a bonus that can be added to a quiz of your choice. If you are satisfied with your score on a quiz, you do not need to solve the corresponding problem on the final. If you are satisfied with your score on all the quizzes, you do not need to take the final.

**Course Goals:**Learn how to describe, analyze and design analog and digital electrical circuits. Develop engineering experience and problem solving and debugging skills. Learn how to use test instruments, computer-based design and simulation tools, and how to collect and interpret experimental data. Develop independent thinking and design skills. Apply to material learnt to the design and implementation of final project.
