Direct Digital Synthesis (DDS) systems generate fine frequency resolution signals over a broad spectrum that are used in a wide variety of applications such as multi-mode RF, communications, measurements and test. A high performance DDS band-pass Digital to Analog Converter (DAC) architecture and implementation is presented that delivers high spectral purity over a narrow-band response. The low power D/A Converter is portable to standard CMOS processes and designed to achieve over 100dB narrow-band SFDR performance using Sigma-Delta (¿¿) modulation and multi-bit current steering techniques. A 3rdorder digital ¿¿ modulator is combined with a 4thorder digital Dynamic Element Matching (DEM) block to shape the noise while calibrating for process mismatch variations. A low silicon area output stage is used to deliver a high performance specification. © 2012 IFIP International Federation for Information Processing.
