A. Learning Outcomes:
Students will demonstrate the ability to:
 Communicate effectively in the language of electronic systems, including correct
understanding and use of technical terms.
 Analyze the characterisitics (input impedance, output impedance, bandwidth, gain, phase
margin) of a circuit that contains a black-box amplifier and external circuitry including
feedback.
 Recall the equations that define the basic operating characteristics of electronic components,
including diodes, bipolar transistors and field effect transistors.
 Compute the bias points of electronic elements including diodes, bipolar transistors, and field
effect transistors, given a circuit diagram and device characteristics.
 Compute the time and frequency domain responses of circuits containing electronic
components.
 Design a circuit that will bias an electronic component at a particular quiescent point.
 Design a basic amplifier having prescribed gain characteristics.
 Effectively apply the principles of feedback to tailor the gain, phase, input impedance, and
output impedance characteristics of an amplifier
B. Topics covered (Syllabus):
 Introduction to electronics: generic amplifier model, basic definitions; decibel notations;
trans-conductance amplifiers, differential amplifier basics
 Operational amplifiers: summing-point constraint, inverting and non-inverting amplifiers,
and Schmitt trigger. Design of simple amplifiers, op amp limitations, gain, bandwidth, openloop and closed loop gain, open and closed loop break frequencies. Op amp frequency
limitations, large signal operations, slew-rate, and full-power bandwidth.
