Abstract

We present a low-power bandgap reference (BGR), functional from sub-1 V to 5 V supply voltage with either a low dropout (LDO) regulator or source follower (SF) output stage, denoted as the LDO or SF mode, in a 0.5-&#x03BC;m standard digital CMOS process with <i>V</i><sub>tn</sub> &#x2248; 0.6 V and |<i>V</i><sub>tp</sub>| &#x2248; 0.7 V at 27&#x00B0;C. Both… (More)
