Abstract : This report is in response to a request to provide an analysis on the design of an ultra-low power integrated circuit which will perform digital filtering on voice bandwidth signals. This chip will contain a 1024-tap linear phase filter with programmable weights, operate at a sample rate of 8 kHz, and will consume a maximum of 7.2 mW power with a 3.6-volt power supply. This monolithic filter will contain: an 8-12 bit a/d internal processing clock oscillator, and the digital filter. This study only reports on the power requirements of the digital filter portion of the chip, although all portions must be considered in the overall power budget. Preliminary device count and die size estimates are presented. The work presented here is based on an earlier study performed by Hughes Research Laboratories (HRL) for NOSC.
