The entry is a class D amplifier made entirely out of discrete digital logic components. I took great pains not to use op amps or transistors or any active devices besides logic gates. Though the amplifier outputs square waves, the process to generate them is entirely analog. As such, this design is an example of using digital gates in an analog way.
Check out the video after the break.
