Abstract :
High speed DACs and ADCs are key components for mm-wave communication systems that apply spectral efficient modulation formats to achieve date rates up to 100 Gbit/s. CMOS converters enable the integration with a mm-wave front-end and a high-throughput DSP on a low-cost system-on-chip. We present CMOS ADC and DAC prototypes with conversion rates up to 36 GS/s, resolutions between 3 and 6 bit and real-time digital interfaces that enable experimental lab setups with the DSP functions implemented on FPGAs.
