ELEX 2120 - Electronic Circuits 1

Electrical and Computer Engineering Part-time Studies Course

School of Energy

BCIT is planning for a substantial return to on-campus activity for the Winter 2022 term as informed by BC Provincial Health Officer guidelines. Refer to each course listing for details.

Course Details

This is an introductory electronic circuit course that provides the foundation for subsequent electronics courses. The course explains how electronic circuits work and how to analyze, design, modify and combine them to perform complex functions. Laboratory work emphasizes logical circuit layout and wiring and the use of common test equipment to analyze and troubleshoot electronic circuits.


COMM 1143 and ELEX 1105 and MATH 1431

Learning Outcomes

Upon successful completion of this course, the student will be able to:

  • Apply (iii) KVL and KCL to calculate the currents and voltages in simple circuits (max. four nodes or three loops) with passive components, independent sources, and one transistor (dependant source). [1, 2]
  • Describe (ii) the electrical characteristics of diode, BJT, and MOSFET with emphasis on different regions of operation. [1]
  • Apply (iii) large-signal model for diode, MOSFET, and BJT to calculate bias voltages and currents in simple circuits. [1, 2]
  • Use (iii) BJT and MOSFET as a switch to turn on/off a low power (max. 1W) load. [1]
  • Apply (iii) small-signal model for diode, MOSFET, and BJT to calculate input/output impedance and voltage gain of a one stage transistor amplifier. [1, 2]
  • Use (iii) the concept of Thevenin (Norton) equivalent circuit to measure voltage gain, input resistance, and output resistance of transistor based amplifier. [1, 5]
  • Apply the definition of 3dB bandwidth and use Bode plots to characterize (ii) the frequency response of an amplifier. [1]

Effective as of Fall 2020
