1 Full-Wave (Bridge) Rectifier
What happens when a diode fails? (Diodes always fail as OPEN circuits)

2 Light-Emitting Diode (LED)

3 Zener Diode

4 Zener Diode

5 Zener Diode Voltage Regulator

6 Transistors Three-terminal devices with three doped silicon regions and two P-N junctions Two basic ways of implementation: Bipolar Junction Transistor (BJT) Field-Effect Transistor (FET)

7 Bipolar Junction Transistors
E C = collector B = base E = emitter NPN transistor

8 Transistors BJT

9 Transistors BJT

10 Transistors BJT PNP NPN

11 Field-Effect Transistors

12 Field-Effect Transistors

13 Transistors FET

14 Transistors FET When VG is positive, electrons in the p-type substrate are attracted to the oxide–silicon interface, and form an n-type conduction channel. The electrical model is represented by resistors in series. The transistor is in its ON state. NMOS

15 Transistors FET When VG = 0, the area underneath the oxide layer is still p-type, which forms a “back-to-back” diode with the n region, as shown in the electrical representation. The transistor is in its OFF state. NMOS

16 Transistors FET PMOS
