Back when broadcast television was first switching over from analog to digital most people needed to get a converter box to watch DTV broadcasts. Remember that abomination that was “HD-Ready”?

For this discussion, the flyback converter used in portable AC-DC supplies is simplified with a new semiconductor material—a gallium-nitride (GaN) high-electron-mobility transistor (HEMT).

One of the most challenging tasks in Analog to Digital Converter (ADC) design is to adapt the cicuitry to ever new CMOS process technology. For digital circuits the number of gates per square mm app.
