Abstract

This paper presents a 12-Bit 250MHz CMOS current-mode Digital to Analog Converter(DAC) with current scalers and dividers. It consist of 4 MSB current scaler, 4 MLSB current divider, and 4 LSB current divider. The simulation results show a conversion rate of 250MHz, DNL/INL of ${\pm}5LSB/{\pm}7LSB$, die area of $0.55mm^2$ and Power dissipation of 27mW at 3.3V
