Abstract :
This paper presents a fully CMOS band-gap reference for extended temperature range (from -50 °C to 160 °C) applications. The proposed solution provides an output voltage of 798 mV with a power supply as low as 1 V. The measured output voltage variations as a function of temperature (-50 °C to 160 °C) and power supply (1 V to 2 V) are 6.64 ppm/°C and 248 ppm/V, respectively. High accuracy is achieved by minimizing the operational amplifier offset. Power consumption is approximately equal to 26 μW (supply voltage = 1 V). Silicon area is 0.02 mm2.
