If you look at a modern printed circuit board (PCB), you will almost certainly see at least two or three rectangular black packages with silver terminals protruding from the edges. For example   Electrical engineers often refer to these packages as components or devices, and for good reason - they look like components, are purchased as components, and often act as components. But if we interpret the term to mean things like resistors, capacitors, inductors, diodes and transistors, engineers will know that they are not actually components. Instead, these black packages are actually circuits.   What is an integrated circuit? A very valuable property of transistors is that they can be very small, which in turn allows us to compress complex functions into a very small physical area. However, a microscopic transistor is not very useful in the macroscopic world: how do we plug it into a breadboard or measure its voltage? How does the assembler place it on the PCB?   The creation of integrate
