1. Introdcution

2. Applications of Op-Amps (Active filter) Question: How do you build a 741 op-amp? What is inside the package?

3. 741 Op-Amp Bipolar junction transistor

4. Order of Presentation Diode – Device Physics – Circuit Design Bipolar junction transistor – Device Physics – Circuit Design Complementary Metal Oxide Semiconductor – Device Physics – Circuit Design

5. Device Physics Electrons are injected into the BC junction Electrons are injected into the B; holes to the E. Electrons are swept across the reversed biased BC

6. Bipolar Junction Transistor Implementation of 7400 Gate (We will learn to work with BJTs in ES230)

7. 2-Input NAND Gate F can only be pulled down if both A=B=1. F will be pulled up if either A or B is 0 V.
