Abstract: A differential reference voltage generator with low power consumption and good performance, which is used in ADC, is introduced.The high performance temperature-compensated reference current is generated with a new structure bandgap, and the current is converted to the needed reference directly through the transconductor buffer.The differential voltage has high precision,low temperature-drift, and good anti-jamming ability.The circuit is realized with the TSMC 0.18μm CMOS process and the die area is 250μm×350μm.The chip has been tested.The power consumption is 0.9mW and the average temperature coefficient of the output differential reference voltage is 9.5e-6K-1.
Key words: bandgap reference, differential reference voltage, temperature compensation
