Why are there components such as capacitors, resistors, diodes and others outside integrated circuits? Couldn't they be integrated on the same chip?
In our Analog Electronics Course, we discussed these problems. We can integrate many components on a silicon chip, but depending on the application, not all of them and therefore, when designing a circuit and we need these components they must be external. Two problematic components are inductors and capacitors. We can only integrate low value capacitors, the same occurring with inductors. So, if we need these components, for example, a high-value capacitor, we need to use an external electrolytic. There is also the case that we need to program the circuit characteristics through an external component. This occurs, for example, with voltage regulators, where the output voltage is determined by one or more external resistors.
