A high-PSRR bandgap voltage reference with temperature curvature compensation used for pipeline ADC

Abstract

In this paper, a new design of bandgap reference is presented. Based on traditional bandgap reference circuits, the new one uses a partial supply voltage produced itself feeding back to the other part to improve PSRR. To achieve excellent temperature coefficient, this bandgap reference applies 2nd-order curvature compensated technique which based on a temperature-dependent resistor ratio scheme.
