Description
Summary:This paper presents the design and measurement results of a low power high linear digital-to-analog converter in 0.13 mum CMOS. It is powered by a single 1.5 V power supply offering rail-to-rail output capability. The DAC circuit is based on segmented resistor strings to scale the bandgap voltage references. The design of the advanced class-AB amplifier with rail-to-rail input/output for analog output buffering is given in details. Techniques to improve resistor string matching performance to 10-bit resolution are discussed. An effective output de-glitching circuitry is presented. The DAC can operate at 2.0 MSPS with power consumption of 0.5 mW.
