Abstract :
In this paper, a high-precision and low temperature coefficient CMOS band gap voltage reference source is presented. Prototype of the circuit is simulated using charted 0.35-μm CMOS process. The power supply is 2.5 V. The output voltage reference exhibits 915.4±0.15 mV variation when the supply changes from 2.0 V to 3.0 V at room temperature. The power dissipation is less than 0.2 mW at 2.5 V supply voltage. The simulated results of this circuit using Eldo of Mentor Graphics Corporation show that the temperature coefficient is about 19-ppm/°C.
