Özet

This paper presents a voltage reference generator architecture and two different realizations of it that have been fabricated within a standard 0.18 mu m CMOS technology. The architecture takes the advantage of utilizing a sampled-data amplifier (SDA) to optimize the power consumption. The circuits achieve output voltages on the order of 190 mV with temperature coefficients of 43 ppm/degrees C and 52.5 ppm/degrees C over the temperature range of 0 to 120 degrees C without any trimming with a 0.8 V single supply. The power consumptions of the circuits are less then 500 nW while occupying an area of 02 mm(2) and 0.08 mm(2), respectively. (C) 2015 Elsevier Ltd. All rights reserved
