inst.eecs.berkeley.eduSo far in EE100 you have seen analog circuits. You started with simple resistive circuits, then dynamical systems (circuits with capacitors and inductors) and then op-amps. Then you learned how circuit elements do not operate the same at all frequencies. Now you will learn about two very important circuit elements – diodes1 and transistors.

These were 600 ohm lines, but they have been very rare for more than 35 years!
