摘要:A computationally efficient, low-power (107.6 mu W @ 1.1 V), small core area (2.82 mm(2) @ 0.35 mu m), 16-band nonuniformly spaced digital filter bank with stop-band attenuation of more than 60 dB is designed and implemented for hearing aid applications using a 0.35 mu m CMOS process. The low computational complexity of the filter bank is achieved using a frequency response masking technique with multiple band-edge shaping filters. The proposed filter bank yields significant improvements in both power consumption and group delay. By coefficient sharing scheme, the implementation of such a filter bank requires only three multipliers.
