摘要/Abstract：
A 1V ultra-low power high precision voltage reference is designed and implemented with UMC mixed-signal 0.18-mum CMOS technology. A novel low-voltage high-precision current mirror is introduced in the voltage reference in order to reduce temperature coefficient and line regulation. Post simulation results show that the reference voltage and total power dissipation are 406.5 mV and 0.83 muW, respectively. Temperature coefficient of the voltage reference is 18.5 ppm/degC when temperature ranges from -45degC to 90degC, while line regulation is 1%/V when the supply voltage ranges from 1 V to 2.4 V. The circuit layout occupies approximately 106 mum times 81 mum.
