    Abstract

    A CMOS-only and multiple-output voltage ref- erence has been proposed and simulated in a standard 0.18 μm CMOS process in this paper. Three reference voltages with their own advantages simultaneously are obtained based on the body bias technology and specific active load. Among the three references, the best temperature coefficient(TC) of 74.8ppm/◦C in the temperature range from -20◦C to 80◦C is obtained without using the resistors and specific devices. By introducing operational amplifier and pushing away the main poles of the circuit, low line sensitivity (LS) of 0.06%/V and high power supply rejection ratio(PSRR) of -73dB at 10Hz are obtained without any filtering capacitor. Besides, due to the subthreshold operation, the supply current is as low as 77nA with a supply voltage down-to 1V.
