Propagation Delay: The Physics That Dictates Digital Speed

TL;DR: Propagation delay () is the finite time between a logic gate's input changing and its output responding — typically a few nanoseconds. The longest such path through a circuit...

Multi-Input Logic Gates: From 3-Input AND to Beyond

TL;DR: A wide AND/OR/XOR gate can be built two ways: cascaded (linear delay, ) or as a balanced tree (logarithmic delay, ). Both use the same number of gates —...

3D isometric diagram of an AND logic gate with labeled inputs and output, and an accompanying timing diagram.

The AND Gate: Foundation of Digital Logic and Decision Making

TL;DR: An AND gate outputs 1 only when every input is 1; otherwise the output is 0. Boolean expression . Despite the simple logic, real AND gates have non-zero propagation...

The Humble NOT Gate: Inversion's Power in Digital Logic

TL;DR: The NOT gate (inverter) takes a single input and outputs its logical complement: . It is the third member of the AND/OR/NOT functionally complete set. Beyond simple inversion, NOT...
