Course Description: The basic physical operation of PN-junction diodes, MOSFET's and Bipolar transistors.  Basic transistor circuit configurations (CE, CC CB, CS, CD, CG). DC bias; small signal analysis. Simple multitransistor circuits: diff-amp; current mirror. Frequency response.

Course Website: http://www.enee.umd.edu/courses/enee312-1/

Course Objectives: The objectives of the class are to develop an understanding the physical mechanisms governing the operation of electronic devices such as the diode and the transistor. Students will then use this information to analyze and design analog electronic circuits.

In this course, we will be covering the following topics:

• Semiconductors materials, doping, electrons and holes;
• Analytical description of drift and diffusion of carriers and continuity equation;
• Basic physical operation of P-N junction operation diodes;
• Bipolar junction transistors (BJTs) physical operation and basic circuit configurations;
• Metal-Oxide-Semiconductor field-effect transistors (MOSFETs) physical operation and basic circuit configurations;
• DC bias of Bipolar and FET fundamental analog circuits;
• Small signal analysis and design of fundamental transistor circuits;
• Multiple transistor circuits, differential amplifiers, current mirrors;
• Active loads and op-amps;
• Frequency response, including the Miller effect;
• Feedback concepts (oscillators and stability).

While we will not be discussing it in class, it is expected that you are familiar with the program PSPICE and are able to use it to enhance your understanding of the various circuits to be presented in class.  Some of the supplementary material on the web site may be in PSPICE form.

Required Texts:

• Microelectronic Devices and Circuits, Clifton Fonstad (copies are $25 at the Engineering Copy Center)
• Microelectronic Circuits, 4^th ed., Sedra & Smith
• Physical Operation of the P-N Junction, Diodes, and Transistors, Jon Orloff (e-text available on course website)
  

Grading:
Your final grade will be based on a prerequisite exam, homework, quizzes, a mid-term exam, and a final exam. The following is a tentative weighting for determining overall grades.

Final exam	40%	Friday, Dec 20 8-10am
Midterm	20%
Quizzes	20%	(including prerequisite exam)
Homework	20%

Homework:  
Homework will be due by the end of class (12:50pm) on the assigned date. Late homework will be accepted until the following class period (2-3 days) but will suffer grading penalties. Late homework must be delivered to me in my office or slid under the door.  Do not put them in my mailbox.  Please staple your assignments together; I will not take responsibility for lost sheets. While I encourage you to discuss course material with other students, the homework problems to be completed independently. If your homework appears to be identical to another student's, you may be asked to demonstrate your understanding of the material to the instructor or TA in an oral quiz. Homework solutions that are not legible will not be graded.

Exams and Quizzes: 
Your final score will be based in part on a prerequisite exam, three equally-weighted quizzes, a midterm exam, and a final exam.  The prerequisite exam will be given during recitation section on Thursday, Sep 12. The dates for the quizzes and midterm will be announced in class at least one and a half weeks in advance.  The final exam will be on Friday, Dec 20, 8:00-10:00 am. Makeup exams are ONLY possible for those with officially documented excuses (i.e. approved by the undergraduate studies office). Exam questions will be based on the material covered in class. All work for long answer questions must be shown in order to receive full credit. The correct answer alone will count towards no more than 20% of the total score on long answer questions. Quizzes will be given during the recitation section.

Office Hours: 
Please come during regular office hours (Wed 3-5pm).  Other times are fine, but by appointment ONLY.  Questions about the homework, grading, or the material presented in class should be first directed to the TA.

Recitation Sections:
The TA will review material and answer questions about class material and homework during the recitation sections. In addition, quizzes will be given during the recitation section. Some supplementary class material may also be given during the recitations.

Course Materials Distribution:
While much of the course material will be distributed in the class lecture, supplementary course material will be available from the class website at:  http://www.enee.umd.edu/class/enee312-1 and via direct email to students in the class.  In the beginning of the course, I will attempt to verify that class notifications are reaching your email address, however, it will be your responsibility to ensure continued reception of class information.  All class announcements will be posted onto the class website as an alternative means of retrieving updated information.
 
Absences:
While it is my intent to respect our diverse community's religious observances, it is the student's responsibility to inform me in writing (email) of any intended absences for religious observances in advance.  Notice should be provided as soon as possible but no later than the end of the second week of classes.

Academic Integrity:
Academic dishonesty will not be tolerated.  All work submitted for grading must be your own.  The University Code of Academic Integrity, which can be found at http://www.inform.umd.edu/CampusInfo/Departments/JPO/, prohibits students from committing the following acts of academic dishonesty: cheating, fabrication, facilitating academic dishonesty, and plagiarism.  Academic dishonesty in this class includes outright copying on homework; however, discussing homework problems and exchanging tips is permissible and also encouraged.  Instances of academic dishonesty will be referred to the Office of Judicial Programs.
