This lesson covers the passive components such as resistors, capacitors, inductors, mutual inductances, transformers, and wires. It explains the difference between passive and active components, and how resistors are made on an integrated surface. The lesson also delves into the concept of resistivity and its units. It further discusses the construction of capacitors, the concept of fringing, and the factors affecting the capacitance of a structure. The lesson concludes with a discussion on how to make capacitors on an IC and the considerations to keep in mind while doing so.

- Passive components do not need a power supply and are mostly linear. They include resistors, capacitors, inductors, mutual inductances, transformers, and wires.
- Resistors on an integrated surface are made out of poly silicon, and their resistance is inversely proportional to the cross-sectional area.
- Capacitors are made of two parallel plates separated by a non-conducting dielectric. The capacitance of a capacitor is given by the formula A*epsilon/d, where A is the area of the plates, epsilon is the permittivity of the dielectric, and d is the distance between the plates.
- Fringing is an effect where the electric field curves towards the other plate at the edges of a capacitor. This effect increases the effective capacitance of the structure.
- When making capacitors on an IC, it's important to consider the area of the capacitor, the distance between the plates, and the perimeter of the capacitor.
