A CMOS Bandgap References Voltage Circuit Using Current Conveyor for Power Management Applications

Abstract

This paper proposes a low power bandgap reference voltage circuit that provides an output reference voltage close to the bandgap voltage having a low output resistance and allows resistive loading. This proposed circuit is design and implemented using the TSMC 0.18μm 1P6M CMOS process. Simulation and measured results verify that the chip size is with power dissipation about 0.1mW, and the operation temperature range formwith temperature coefficient about . The chip supply voltage can from 1.3 to 1.8V with PSRR about 70 dB, and its output reference voltage can stable on .
