Abstract

We describe a bandgap circuit capable of generating a reference voltage of 0.730V. The circuit is implemented in 0.18/spl mu/m CMOS technology and operates with 0.9 V supply voltage, consuming 5/spl mu/A current. The circuit achieves 7ppm/spl rho/K of temperature coefficient with supply voltage range from 0.9 to 1.5V and temperature range from 0 to 60/spl deg/ centigrade.
