Untrimmed 6.2ppm/C bulk-isolated curvature-corrected bandgap voltage reference
The paper proposes a block bulk isolation strategy for triple-well processes. The substrate noise sensitivity of the designed BGR output is improved more than 100dB up to 100MHz. The designed BGR achieves the best untrimmed temperature coefficient with minimum area. Its noise performance is equivalent to the best reported [14] while occupying 1/2.5 the area.
