We look at a few
We look at a few more transistor circuits: the emitter follower, the push-pull amplifier, and the saturated switch.
We learn what they do and how to calculate their voltage transfer functions.
We learn the danger of switching an inductive load with a transistor, and pull 127 volts off a AA flashlight battery.
Schematics are on the project GitHub: https://github.com/kennykb/kevins-cav...
TIMELINE
00:00 Intro
00:50 The emitter follower
03:04 Emitter follower with split supplies
04:00 Kevin can be bit absent-minded.
07:06 Emitter follower under load
08:55 Push-pull amplifier
10:23 Fixing crossover distortion
12:15 Saturated switch
13:39 127 volts from a flashlight battery?
14:38 Taming flyback
16:09 Outro
