Abstract

In this paper, a modified low-votlage CMOS bandgap voltage reference with CTAT compensation is presented. The proposed structure doesn't use PTAT current. The proposed structure is more simple than the existing structure and doesn't use the eighteen BJT. The modified low-votlage CMOS bandgap voltage reference with CTAT compensation has been successfully verified in a standard 0.18um CMOS process. The simulation results have confirmed that, with the minimum supply voltage of 1.25V, the output reference voltage at 549mV has a temperature coefficient of 12ppm/°C from 0 ^°C to 100 ^°C.
