Abstract :
A 0.4-V UWB digital baseband processor has been fabricated in a standard-VT 90-nm CMOS technology. The base-band processor operates at an ultra-low supply voltage to reduce energy consumption and utilizes a highly parallelized architecture to meet throughput constraints. While ultra-low voltage operation is usually limited to low energy, low performance applications, this work examines how it can be applied to low energy, high performance applications. Measured results for a 20-pJ/bit 100-Mbps UWB baseband processor are presented. Architectural techniques and design methodologies for reducing additional complexity due to parallelism are discussed.
