Abstract :
A sub-1-V self-biased low-voltage low-power voltage reference is presented for micropower electronic applications. And the proposed circuit has very low temperature dependence by using a back-gate connection MOSFET. An Hspice simulation shows that the reference voltage and total power dissipation are 181 mV and 1.1 muW, respectively. The temperature coefficient of the reference voltage is 33 ppm/degC within a temperature range from -40 to 100 degC. The supply voltage dependence is -0.36 mV/V (Vdd=0.95~3.3 V). Supply voltage can be as low as 0.95 V in a standard CMOS 0.35 mum technology with threshold voltages of about 0.5 V and -0.65 V for n-channel and p-channel MOSFETs, respectively
