A 302 uW CMOS Temperature Sensor to compensate frequency drift for an oscillator

The proposed work is a fully-integrated temperature sensor with low power consumption. The frequency drift of the oscillator will be compensated by this designed CMOS temperature sensor. The bandgap reference circuit was implemented to generated required control voltage and slope. The work demonstrated required control voltage and slope can be generated by changing variable resistors. The deigned CMOS temperature sensor dissipate 302uW while exhibiting inaccuracy of -$0.001^{\mathrm {o}}\text{C}$ and +$0.032^{\mathrm {o}}\text{C}$ over a temperature range between -10 to 90 0C and voltage supply variations of 10%130
