摘要：
A 1V ultra-low power high precision voltage reference is designed and implemented with UMC mixed-signal 0.18-um 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 406.5mV and 0.83uW, respectively. Temperature coefficient of the voltage reference is 18.5ppm/degrees C when temperature ranges from -45 degrees C to 90 degrees C, while line regulation is 1%/V when the supply voltage ranges from 1V to 2.4V. The circuit layout occupies approximately 106umx81um.
