#67: Basics of Common Emitter Amplifier Gain and Frequency Response with Measurements

This video shows a simple common emitter amplifier based on a 2N2222 NPN transistor, and reviews how to calculate the gain and frequency response of the circuit. The video is NOT intended to take a deep dive into the design considerations for the amplifier (The Signal Path Blog site already did a fine video on that). I discuss the basic equations for calculating the the in-band gain, as well as the low- and high- corner frequencies of the frequency response. All of these parameters - DC bias levels, bias currents, in-band gain and frequency response are then measured and shown.
