Week 8 — Transistors for Switches and Oscillators
Week 9 — Transistors for Amplification — Start Op Amps
- Tuesday, March 24 — Skip to p. 59 and as the homework before class, build the two circuits on that page — We carefully studied the first three pages of a book section on Bipolar Junction Transistors — Our goal was to understand (a) the depletion region (reverse bias) at the base(p)-collector(n) junction, (b) the forward bias at the emitter(n)-base(p) junction, (c) and most importantly, the explanation of the multiplier effect wherein only a small fraction of the electrons put by the voltage source into the emitter join with holes in the base, or come out the base lead (most go across the base and are swept into the collector) — Then we built the one-transistor amplifier on p. 61
- Friday, March 27 — Before class, build your second one-transistor amplifier on p. 62 — We will try to understand how the multiplier effect in our one-transistor circuits work — We will understand the capacitor/resistor combinations that make a low-pass filter — Negative feedback theory for op amps in non-inverting configuration
Week 10 — Continue Op Amps — Low-Pass Filters
- Tuesday, March 31 — Before class, build your first operational amplifier circuit on p. 72 — In class, we will build the circuit on p. 73 which has an op amp in an inverting configuration — Negative feedback theory for op amps in inverting configuration
- Friday, April 3 — First we’ll go over your questions on our collected problems — Second, we will understand the charge and discharge cycles that make a low-pass filter work — We will measure properties of our op amps using multimeters
Week 11 — Continue Op Amps — High-Pass Filters — Special Project (Start AM/FM Radio Kits)
Week 12 — Power Transfer — Continue Assembling AM/FM Radio Kits
