-This page is very research orientated and information on it should not be trusted.
-TODO: this page should eventually have only compound logic gates, but is currently a sandbox for basic components. I'd like to substitute out these pictures for ones free of copyright issues to avoid any potential issues.

-====== Resistor ======
-Resistors seem to be grouped on islands with many other resistors. Resistance is a factor of the length of the trace, dopant, etc.

-In MOS circuitry, resistors are avoided as much as possible as it is often much more cost effective to utilize transistors to form an equivalent circuit.
-====== Capacitor ======
-This component has an unknown appearance. Think it was difficult to form in early BJT circuits, so it is unlikely to be seen at all.
-====== Logic gates ======
-One of these is likely NAND and other is NOR.
