ULP Bandgap Voltage Reference - 210nA consumption, 40ppm/ºC - Silterra 0.18um

This macro-cell is an ultra-low-power bandgap voltage reference (1.23V) with low temperature coefficient (>40ppm/ºC) consuming 210nA. A 5-bit digital bus allows TC adjust against process variations. It provides a built-in 10nA PTAT current reference with 4 outputs.

The core can be easily retargeted to any other CMOS technology because it uses typical devices of standard CMOS technologies (MOS and PN junctions).
