As network traffic is still growing at an enormous rate, ultra-broadband converters are of uttermost importance. Especially the analog front-end section of these converters, i.e. the analog input of ADCs and the analog output of DACs, imposes severe challenges on the circuit design. SiGe-BiCMOS the technology of choice for the implementation of the these analog front ends, because SiGe bipolar transistors offer both extremely high cutoff frequencies needed for the converter bandwidth as well as large scale integration capability as needed for the complex converter circuitry. The EU/ECSEL project TARANTO does research on both the device speed enhancement as well as on advanced circuit topologies and designs for ultra-broadband analog front-end circuits for AD and DA conversion. This presentation will present solutions for implementing ultra-broadband ADC and DAC front-ends and discuss the main challenges for the corresponding circuit design. We will show practical circuit designs realized in TARANTO by URM1, USTUTT, USAAR and MICRAM as well as a test setup from NOKIA. For the data link receiver, we present very broadband SiGe BiCMOS analog front-end circuits for synchronous (STI) and asynchronous (ATI) time interleaving of AD converters. The STI front-end applies current mode integrating samplers whereas the ATI front-end applies mixers and filters. For the data link transmitter, an ultra-high-speed single-core SiGe BiCMOS DAC core will be shown. Moreover, we introduce the concept of D/A time interleaving with analog multiplexer circuits. Finally, we present a testbed for the test of a STI ADC front-end.
