This paper describes a CMOS voltage reference using only resistors and transistors working in weak inversion,without the need for any bipolar transistors.The voltage reference is designed and fabricated by a 0.18 μm CMOS process.The experimental results show that the proposed voltage reference has a temperature coefficient of 370 ppm/℃ at a 0.8 V supply voltage over the temperature range of-35 to 85 ℃ and a 0.1％ variation in supply voltage from 0.8 to 3 V.Furthermore,the supply current is only 1.5 μA at 0.8 V supply voltage.
