Low power consumption CMOS digital matched filter - an application example of the Plastic Hard Macro technology

摘要

A low power consumption Digital Matched Filter (DMF) was designed in 1.8V operation 0.18μm CMOS technology. An 8-bit input 256-tap DMF showed 0.38mW/MHz low power characteristics, that just fitted a portable phone use. Special features are the PN code shifting architecture, an application of the Plastic Hard Macro IP, that is low energy-delay products arithmetic IPs, and clock handling optimizations. The maximum operation frequency was just below 200MHz. A high layout density, 71k gates/mm{sup}2 was also attained.
