Future of analog in the VLSI environment

It is argued analog circuits will remain irreplaceable for the implementation of the interface circuitry between digital processing and the external world. Most of their characteristics can be improved with scaled-down processes. Analog circuits will also compete with digital and will remain advantageous for low precision signal processing. Since little precision is required to carry out many cognitive tasks, analog VLSI (very-large-scale integration) will dominate in the implementation of many types of neural networks.<<ETX>>
