Learning outcomes

The course focuses on basic amplifier building blocks and circuits for wireless communications. Upon completing the course the student understands and can analyze the most important amplifier circuits. The student knows: - The basic concepts of semiconductor physics needed to understand transistor (BJT and MOS) operation; - The basic transistor amplifier stages (common emitter/source, common collector/drain and common base/gate) and their operation as well as how to do small-signal analysis of these amplifiers; - Principles of feedback and how it affects amplifier circuits as well as operation of most important oscillator circuits based on feedback; - Operation of different classes of power amplifiers, i.e. A, B, C and other higher classes; - The basic operation of differential and cascode amplifiers and how to improve their operation - Basics of filter transfer functions and design; - How to use OrCAD PSpice for simulating basic amplifiers and oscillator circuits - How to perform basic oscillator measurements using oscilloscopes and spectrum analyzers and how to automate the measurement process using HP-VEE software.
