A 400-mV UWB Baseband Processor

The baseband processor performs acquisition and demodulation of an UWB packet with a throughput of 500-MS/s for a data-rate of 100-Mb/s. It operates at an ultra-low supply voltage of 400-mV to achieve 20 pJ/bit, and utilizes a highly parallelized architecture to meet throughput constraints. It was fabricated in a standard-VT 90-nm CMOS process.
