Current Steering DACs
Switched current digital-to-analog converter (DAC) designs have become the architecture of choice for submicron CMOS technologies. Current steering DACs are able to operate at very low power supply voltages (<1V) and benefit from the switching speed of submicron gate length MOS transistors while making use of a standard CMOS process. The high sample rate of current steering DACs enables the design of oversampled DACs where linearity is traded over bandwidth (e.g. Audio DACs) with dynamic element matching (DEM) techniques.
Segmented current steering DACs in combination with background calibration are the basis for our 14bit 800MS/s Nyquist rate DAC designs.
