Abstract

CMOS Reference Voltage Generator(RVG) is designed to possible CMOS process without additional process steps. It is possible to compensate the temperature of RVG by using PTAT(proportional to the absolute temperature). Temperature compensation is profitable because $\mun$ (electron mobility) is used. When VDD sweeps from 3V to 7V, variation ratio of Vref is 0.3125mV/V. Also temperature variation ratio of Vref is $047.1ppm/^{\circ}C$ during sweeping from $0^{\circ}C$ to $100^{\circ}C.$ Power Consumption is $50.3\muW.$
