A Study and Comparison of Low Power CMOS Voltage Reference

Low voltage and low power are two important design criteria in both the analog and digital systems. It is expected that the whole system will be able to operate down to a single 1 V supply in the near future. A voltage reference, as one of the core functional blocks in both analog and digital systems should be able to operate from a single 1 V supply for both systems. This paper presents a study and comparison between CMOS low power voltage reference in terms of voltage independent over the temperature. The reference voltage circuits are designed &simulated in SPICE with0.35 um technology with supply voltage of 2.5V & 1.8V respectively.
