R.F.里昂和C.A.米德(Trans.Acoust，Speech，Signal Processing，Vol.36，No.7，p.1119-34,1988)在亚阈值模拟VLSI中使用二阶滤波段的级联来实现早期听觉处理的低功率、实时模型。许多硅耳蜗片的经验使我们能够识别出许多重要的设计问题，即动态范围、稳定性、器件不匹配和紧凑性。本文针对这些问题对原设计进行了讨论，并对其电路和版图技术进行了描述，这些技术显著地提高了其性能、健壮性和效率。测试芯片的测量结果证实了性能的提高。&gt；
The original 'Analog electronic cochlea' of R.F. Lyon and C.A. Mead (Trans. Acoust., Speech, Signal Processing, vol.36, no.7, p.1119-34, 1988) used a cascade of second-order filter sections in subthreshold analog VLSI to implement a low-power, real-time model of early auditory processing. Experience with many silicon-cochlea chips has allowed the identification of a number of important design issues, namely dynamic range, stability, device mismatch, and compactness. In this, paper, the original design is discussed in light of these issues, and circuit and layout techniques are described which significantly improve its performance, robustness, and efficiency. Measurements from test chips verify the improved performance. >
