Abstract :
This paper presents a precise compensated bandgap reference without resistors. This bandgap reference uses an improved voltage-transfer unit instead of resistors. A current proportional to Tα (α is a constant) is produced to compensate for the higher order of the VEB. This bandgap reference is based on 0.5μm n-well CMOS technology. The supply voltage is 5V, working from -10°C to 90°C, the effective temperature coefficient of the output voltage is only 7 ppm/°C, and the maximum power dissipation is 0.76mW.
