A 2.2 V-voltage reference circuit design with TC of 35.49 ppm/o C for low power DAC applications

Abstract

Constant voltage reference is the basic for the digital data conversion from analog data where rich digital data applications are important. It acts as a bench mark reference for the data to convert. In this paper we have designed a BGR supplying 1.4 V using 5 V supply and generated a constant supply of 2.2 V with additional ciruit using SCL 180 nm technology where the TC is 35.49ppm/oC and the mean and SD of Monte carlo resulted as 74.81 and 11.09 respectively, which can be used as a benchmark reference for DACs.
