Abstract
A novel controllable current attenuator for completely integrable hear ing aids is presented. Much attention has been paid to obtaining good signal to noise ratio and low distortion. The attenuation can be contr olled logarithmically. The attenuator is designed for a supply voltage of 1-1.3V and can be used with both symmetric and asymmetric signal p aths. The maximal supply current is 50 muA.
