Title
An ultra-low-power, low-voltage electronic audio delay line for use in hearing aids
Abstract
In this paper, the design of an electronic audio delay line, realized with a second-order all-pass filter, is presented. The designed filter is primarily intended for use in hearing aids, to provide directivity by a specially designed microphone array. The filter operates at a supply voltage of as low as 1.8 V. The simulated and measured total quiescent current is 0.9 /spl mu/A. Owing to current c...
