UELE 121A - Solid State Devices and Circuits I 24 Noncredit Contact Hours 14 Lecture Hours 10 Lab Hours
This course introduces learners to the theory of operation of semiconductor diodes and transistors. It also covers bipolar junction transistor biasing and load-line analysis.
Course Learning Outcomes:
- Define the following electronic terms: intrinsic semiconductor, n-type material, p-type material, and doping.
- Describe the operation of both a forward and reverse-bias diode.
- Describe the functions of the base, emitter, and collector of a bipolar transistor, and how they are biased.
- Identify and describe the various forms of transistor biasing and how an operating point is selected.
- Apply the scientific method in inquiry and deduction relating the laws, theories, and axioms of solid-state devices to specific laboratory experiments.
- Explain the concept of open-loop vs closed-loop responses of an amplifier and relate to amplifier stability.
- Calculate voltage gains, input and output impedance, and bandwidths for inverting and non-inverting operational amplifier (OP AMP) circuits
