(I didn't start this Wiki before I had watched several of these videos. I might someday catch back up on Lectures 1-5.)

[Lecture 6 - Nonlinear Analysis|http://ocw.mit.edu/courses/electrical-engineering-and-computer-science/6-002-circuits-and-electronics-spring-2007/video-lectures/embed06/]
* Creates a device designed to send a signal over a garage door sensor
* Unfortunately, the thing sounds terribly, because it transmits non-linearly. The waveform gets distorted. Demo starts around 38:15

[Lecture 7 - Incremental Analysis|http://ocw.mit.edu/courses/electrical-engineering-and-computer-science/6-002-circuits-and-electronics-spring-2007/video-lectures/embed07/]
* Fixes problem with Lecture 6's circuit. (Student solutions involved going digital, which is over-solving the problem in this case.)
* Non-linear curves are linear in a small enough segment. So what you do is "squish" and "bump".
** Squish = Attenuate the signal so that it has a smaller range
** Bump =  Raise the minimum signal so that the swing is higher up on the response curve of the component
* Then you just amplify on the other end. Really neat.
* AKA Small-signal method

[Lecture 8 - Dependent sources and amplifiers|http://ocw.mit.edu/courses/electrical-engineering-and-computer-science/6-002-circuits-and-electronics-spring-2007/video-lectures/embed08/]
* Reminder about circuit analysis:
** Composition (Thevenin/Norton analysis) can often simplify
** Node method is always there when all else fails. The "Workhorse"
* Amplification (aka Gain, Increase in signal strength, etc.), motivating examples:
** Greater noise immunity of stronger signal
** Cell phone, Antenna -> Low-Noise Amplifier
** Digital signal amplification (keeping it within tolerances
* Voltage-Controlled Current Source (VCCS), CCCS, CCVS, VCVS; Examples:
** Independent Current Source: Current source + a resistor, simply V{sub}R{/sub} = IR (24:00)
** Dependent Current Source (VCCS): Voltage source + Current source, I = f(V) (25:00)
*** + Simplified circuit drawing for VCCS (27:00)
** V{sub}0{/sub} = V{sub}S{/sub} - kR{sub}L{/sub}/2 * (V{sub}I{/sub} - 1){sup}2{/sup}
** (see 36:48)
** Very important equation for 6.002
** == an amplifier
** Curve examination (45:00)
** Real-life departure from equation (49:00)

[Lecture 9 - MOSFET amplifier large signal analysis - part 1|http://ocw.mit.edu/courses/electrical-engineering-and-computer-science/6-002-circuits-and-electronics-spring-2007/video-lectures/embed09/]
* Review ends at ~9:00
* VCCS, e.g. MOSFET
[http://panoptic.com/rking/file/up/mosfet-vccs.png]
** V{sub}GS{/sub} < V{sub}T{/sub}, D-S = like open circuit
** V{sub}DS{/sub} < V{sub}GS{/sub} - V{sub}T{/sub}
** Resistive behavior, "SR Model"
** Digital
*** Graphs @ 18:00, mentions, "A straight line is resistor-like behavior"
** V{sub}DS{/sub} >= V{sub}GS{/sub} - V{sub}T{/sub}, D-S = like current source: I{sub}D{/sub} = k/2 * (V{sub}GS{/sub}-V{sub}T{/sub}){sup}2{/sup}
*** Shows curve for higher V{sub}GS{/sub}, MOSFET saturates
*** (Youtube comment says: "For a MOSFET, the saturation region is the region where the FET acts like a current source. It is the opposite name used for a BJT transistor. In a BJT this same region is called the linear region.")
* MOS Amp ([34:00|http://www.youtube.com/watch?v=Nijya-QJ45Y#t=34m], diagram complete near [37:30|http://www.youtube.com/watch?v=Nijya-QJ45Y#t=37m30s])
