# 30.002 Circuits & Electronics

Home / Education / Undergraduate / Courses / 30.002 Circuits & Electronics The SUTD EPD pillar course, Circuits and Electronics, introduces the fundamentals of the lumped circuit abstraction. Topics include: resistive elements and networks; independent and dependent sources; switches and MOS transistors; digital abstraction; operational amplifiers; energy storage elements; dynamics of first and second order networks; design in the time and frequency domains; analog and digital circuits and applications. Design and lab exercises are significant components of the course.

#### Goal

The ultimate goal of this course is to equip students with the basic skills and confidence to analyze simple circuits or parts of a complex circuit, and to design their own custom circuitry for specific functions.

#### Learning Objectives

• Define and explain the basic electrical engineering principles and abstractions on which the design of electronic systems is based, including lumped circuit models, digital circuits, and operational amplifiers.
• Use these engineering abstractions to analyze and design simple electronic circuits.
• Formulate  and  solve  differential  equations  describing  the  time  behavior  of  circuits containing energy storage elements.
• Use  physical  intuition  to  describe  the  approximate  time  and  frequency  behavior  of circuits containing energy storage elements.
• Apply simple  models  to  represent  non-linear  and  active  elements such  as  the MOSFET in circuits.
• Build circuits, measure circuit variables (using tools such as oscilloscopes, multimeters, signal generators),  compare  the  measurements with  mathematical models, and explain the discrepancies.
• Appreciate the practical significance of the systems developed in the course.

#### Measurable Outcomes

• Employ simple lumped circuit models for resistors, sources, inductors, capacitors, and transistors in circuits.
• Analyze circuits made  up  of  linear  lumped  elements resistors  and  independent sources using  techniques  such  as  the  node  method,  superposition  and  the Thevenin method.
• Employ Boolean algebra to describe the function of logic circuits.
• Design circuits which represent digital logic expressions, such as a gate-­‐level digital circuit to implement a given Boolean function.
• Check static discipline constraints in circuits. For example, determine if the circuit representing a gate provides adequate noise margins.
• Determine the output produced by a circuit for a given set of inputs using the switch resistor model of a MOSFET.
• Perform a small-­signal  analysis of an amplifier using small signal models for the circuit elements.
• Calculate the time behavior and frequency response of first order and second order circuits containing resistors, capacitors and inductors.
• Construct simple gates, amplifiers, or filters in the laboratory.
• Determine in the laboratory the time-domain and frequency domain behavior of an RLC circuit.
• Use operational amplifier models in circuits which employ negative feedback.
• Use complex impedances to determine the frequency response of circuits.
• Determine the power dissipation in digital gates and employ CMOS technology to reduce static power losses.
• Predict how a given circuit will affect an audio signal in the laboratory given the frequency response of the circuit.
