Learning Objectives

After completing this chapter, you should be able to:

• Explain the differences between voltage gain, current gain and power gain.
• Describe a basic voltage amplifier model using voltage gain, input impedance and output impedance.
• Determine the effects of source and load impedance on system gain and explain how they interact with an amplifier's input and output impedance.
• Describe and distinguish the concepts of noise and waveform distortion.
• Define the concept of output compliance.
• Discuss the frequency limits of an amplifier in general terms.
• Define Miller's Theorem.
