Bandgap voltage reference (output voltage 0.4 V)

Overview

The bandgap voltage reference generates temperature-compensated voltage due to mutual compensation of temperature dependence of bipolar diodes and resistors. It is a simple to configure and operate block, combining good parameters accuracy, small area and low current consumption. The block consists of bandgap, buffer and current sources. The bandgap produces on pin out voltage level around 0.4 V, which adjusted by a trimming codes. The buffer repeats the value of the reference voltage. Signals, en_vbgbuf and en_testmode, control the buffer. Each current source delivers a current of 250 nA.
The block is designed on Global Foundries CMOS 55 nm technology.
