Abstract :
A 10-bit folded multi-LSB decided resistor string DAC is presented. The proposed circuits uses the LSBs of the input digital words to decide the output voltage, which can significantly reduce the number of unit resistors up to 75% compared with the traditional resistor string DAC. The measured results show that the INL is less than 0.73 LSB and the maximum DNL is 0.26 LSB. The active chip area is less than 0.25 mm2
