## AI overview

The article identifies the featured chip structure as a bandgap voltage reference built around paired NPN transistors. It explains how the circuit maintains a near-constant voltage and why dummy transistors surround the active devices.

## Source excerpt

The structure in question for last month's ware are a pair of NPN transistors that form the core of a bandgap voltage reference circuit. As its name implies, a bandgap voltage reference generates a near-constant voltage for use inside chips. The voltage is intended to be fairly constant over process variations, temperature variations, and power [...]
