Abstract
This paper presents an ANSI S1.11-compliant filter bank for digital hearing aids, of which the power consumption is minimized through algorithmic, numerical and architectural optimizations. This filter bank has been implemented and fabricated using the TSMC 0.13 mum CMOS technology. The transistor-level simulations show that the power dissipation is only 79 mu W for 24 KHz & 18-band audio processing.
