Implementation of Low Bandgap Reference Voltage Circuit for Power Management Applications

Abstract:

This paper proposes a low bandgap reference voltage circuit with low temperature coefficient and independent of suply voltage for applications to power management IC. This proposed circuit is design and implemented using the TSMC 0.35μm CMOS 2P4M process. Based on simulated and measured results , the chip size is 20.6000.680mm with power dissipation about 3.3mW, and the operation temperature range form 0Cto 100C with temperature coefficient about 9.29/ppmC. The chip suply voltage can from 2.9V to 3.3V with PSRR about 44.2 dB, and its output reference voltage can stable at 0.65V.
