| description | This paper presents a new low-power Hearing Aid Front-end based on an analog wavelet transform signal processing. The system consists of an analog wavelet filter bank and an Automatic Gain Control (AGC), with a new topology for the decision logic and a new circuit design for the Programable Gain Amplifier (PGA). From simulation results, using a 0.18um CMOS technology, the proposed circuit shows very good performance with respect to Signal-to-Noise Ratio (SNR) and loudness behavior in an ultra low-power environment. |
