Analog VLSI and neural systems
- C. Mead
This chapter discusses a simple circuit that can generate a sinusoidal response and calls this circuit the second-order section, which can be used to generate any response that can be represented by two poles in the complex plane, where the two poles have both real and imaginary parts.

It is shown that for many problems, particularly those in which the input data are ill-conditioned and the computation can be specified in a relative manner, biological solutions are many orders of…
Winner-Take-All Networks of O(N) Complexity
A series of compact CMOS integrated circuits that realize the winner-take-all function using only O(n) of interconnect and a circuit that computes local nonlinear inhibition is modified.
An analog electronic cochlea
An analog electronic cochlea has been built in CMOS VLSI technology using micropower techniques and Measurements on the test chip suggest that the circuit matches both the theory and observations from real coChleas.

A Low-Power Wide-Linear-Range Transconductance Amplifier
The linear range of approximately ±75mV of traditional subthreshold transconductance amplifiers istoo small for certain applications—for example, for filtersin electronic cochleas, where it is…
Analog VLSI Implementation of Neural Systems
A Neural Processor for Maze Solving and Issues in Analog VLSI and MOS Techniques for Neural Computing are discussed.
Analog VLSI Phototransduction by continuous-time, adaptive, logarithmic photoreceptor circuits
This article aims to provide a photoreceptor that can be used as a front end transducer in more advanced research on neuromorphic systems, and to inspire people to build low-power, integrated commercial vision devices for practical purposes.
A Low-Power Wide-Dynamic-Range Analog VLSI Cochlea
Low-power wide-dynamic-range systems are extremely hard to build. The biological cochlea is one of the most awesome examples of such a system: It can sense sounds over 12 orders of magnitude in…
