Design Of A BUlk-ISolated BAndgap REference With 3.7 Ppm/Degrees C Tc In 0.35-M TRiple-WEll Cmos PRocess

open access: yes, 2017
A bulk-isolated curvature-compensated bandgap voltage reference (BGR) compatible with triple-well CMOS technologies is presented in this paper. Verification results of the proposed BGR implemented in a 0.35-mu m 3.3-V triple-well CMOS technology demonstrate that the BGR achieves a reference voltage of 220.4mV with an average temperature coefficient (TC)
