Open publisher page 11 citations

Abstract

This paper presents an integrated bandgap reference circuit which is addressing low current consumption and a wide supply voltage range, using a current mode structure. Embedded in a sophisticated Power Management Unit (PMU) for a GNSS receiver, this bandgap reference has an output of 0.60 V and it can reach a temperature coefficient of 33 ppm/°C in the range from -40 °C to 125 °C. With a 1.4 V supply voltage, the power is only 3.5 μW and the PSRR is 57 dB at DC frequency. Occupying 0.125 mm2 chip area, this bandgap reference has been implemented in the CMOS 28 nm technology from Globalfoundries and successfully validated in the lab.
