Design Low Quiescent Current of CMOS Voltage References
Lai Xinquan · Dianzi qijian · 2007
A type of low quiescent current CMOS voltage reference circuit is designed on the basis of the traditional Bandgap Reference,in order to realize low power,special low quiescent power.It is designed on the basis of the concept of CMOS transistor operating in weak inversion region and the principle of the saturation of drain current being an exponential function of the Voltage.The voltage reference can provide a predictable reference and a low static current.With high-resolution of ±2% and low temperature of 18.9 ppm/℃.The stimulation results show that power consumption is 1.2 μW when the output voltage is 1.109 V and the working voltage 3 V.
