Abstract :
Performance limitations and the required trade-offs in the design of single-ended log-domain filter circuits are analyzed. Second-order filters based on a new log-domain integrator circuit are adapted for use in a silicon cochlea. The results demonstrate that detailed simulations are essential for accurately predicting log-domain circuit performance. Analysis shows why instantaneous companding does not lead to high dynamic range in single-ended log-domain filters
