An Integrated Circuit is a collection of circuit elements all together on one piece of silicon. Example elements include: transistors, for example MOSFETS resistors capacitors inductors Here is an example of a fairly small IC, a type of amplifier called an Op-Amp. The image is from zeptobars The orange zig-zag elements are resistors, the large areas at the top are capacitors, the squares with circular elements in their centres are bipolar transistors, and the thin silver elements are wires jo...
