Document Summary
Final exam study guide (importance: doing better: full-wave diode bridge, the diode in the rectifying circuit simply prevented the negative swing of voltage from conducting. Acts like a reservoir to supply current during low spots. Voltage regulator smoothes out remaining ripple: voltage regulator: setting the voltage, can trim down ripply voltage to precise, rock-steady value, now things get complicated! We are now in the realm of integrated circuits (ics) Ics contain resistors, capacitors, diodes, transistors, etc: transistors: a brief glimpse, transistors have made our modern world possible, sort-of like diodes end-to-end (npn and pnp junctions. But the sandwiched junction is very thin, and this is important: a small current on the base can control a large current flowing from. Collector to emitter : can be used as an amplifier. Make a weak signal stronger: or used as a switch. Pedal-to-the-metal saturation regime: both are incredibly useful, operational amplifiers (op-amps)
