Lecture 6 - Nonlinear Analysis

• 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

• 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

• 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_R = IR (24:00)
• Dependent Current Source (VCCS): Voltage source + Current source, I = f(V) (25:00)
• + Simplified circuit drawing for VCCS (27:00)
• V₀ = V_S - kR_L/2 * (V_I - 1)²
• (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

• Review ends at ~9:00
• VCCS, e.g. MOSFET

• V_GS < V_T, D-S = like open circuit
• V_DS < V_GS - V_T
• Resistive behavior, "SR Model"
• Digital
• Graphs @ 18:00, mentions, "A straight line is resistor-like behavior"
• V_DS >= V_GS - V_T, D-S = like current source: I_D = k/2 * (V_GS-V_T)²
• Shows curve for higher V_GS, 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, diagram complete near 37:30)
