Session 29 overview: Data converters for wireless systems: Data converters subcommittee

Analog-to-digital converters for wireless systems continue to improve in noise and distortion performance, sample rate, and integration. This steady advance allows them to move closer to the antenna and digitize an increasing number of communication channels. Two of the ADCs in this session employ continuous-time delta-sigma modulators while one uses a pipelined architecture. The first paper addresses the challenges posed by large out-of-band blocker signals. The second paper tackles the high dynamic range and low noise floor requirements inherent to modern communication channels. The final paper employs new background calibration techniques, including one that compensates for nonlinear kickback resulting from the input sampler. The impressive performance advancements in these works confirm the effectiveness of the design techniques.
