IC
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 joining these components together. Such a circuit could have been made using discrete components on a circuit board, but it would have higher cost and lower performance. By integrating all of these elements together, the cost and performance are improved.
From wikipedia: There is no consensus on who invented the IC. The American press of the 1960s named four people: Kilby, Lehovec, Noyce and Hoerni; in the 1970s the list was shortened to Kilby and Noyce.
Course feedback
I wanted to get my hands dirty and I think your course sums up the whole experience from the ground up. You start by understanding how MOFETs work, get hands-on with Verilog and then all the way to the stage where you can be part of the ASIC shuttle.
