Multi-Dimension Logarithmic Number System Digital Filter Bank

A new filterbank processor algorithm for a digital hearing instrument based on the Multi-Dimensional Logarithmic Number System (MDLNS) with a low power structure. The processor has integrated binary to MDLNS converters. The design has been optimized for timing; testing shows very competitive power comsumption and area requirements to current binary filter banks. Implemented on TSMCs 0.18Ám CMOS process.

Primary Designers: Hongbo (Jennifer) Li
