A CMOS resistorless bandgap reference with minimized current consumption

Abstract

This paper presents a resistorless bandgap reference with minimized quiescent current, designed in a CMOS 0.35um/5V technology. The circuit relies on strong inversion operation, and the “inverse function”, achieving first order temperature compensation. Simulation results indicate 20ppm/deg.C between -40deg.C to 125deg.C, 6uA quiescent current and 2.8V minimum supply voltage.
