In this paper we compare computational power of two models of analog and classical computers. As a model of analog computer we use the model proposed by Rubel in 1993 called the Extended Analog Computer (EAC) while as a model of classical computer, the Turing machines. Showing that the Extended Analog Computer can robustly generate result of any Turing machine we use the method of simulation pr...

A hybrid architecture for neural coprocessing is presented. A fixed set of analog multipliers and capacitors (analog memory) emulates Multilayer Perceptrons through digitally-controlled multiplexing. Parallelism is partially preserved, then, without direct analog implementation of the whole structure. Details of system VLSI implementation are given, along with simulation results that validate s...

a high accurate and low-voltage analog cmos current divider which operates with a single power supply voltage is designed in 0.18µm cmos standard technology. the proposed divider uses a differential amplifier and transistor in triode region in order to perform the division. the proposed divider is modeled with neural network while tlbo algorithm is used to optimize it. the proposed optimization...

Basic concepts of fault diagnosis in analog and mixed (analog and digital) electronic systems by means of the simulation-before-test approach, the so called dictionary approach, have been presented. Special attention has been paid to application of artificial intelligence tools, such as: artificial neural networks, fuzzy sets and evolutionary computing. Key-Words: Analog electronic fault diagno...

This paper presents an all-analog iterative decoding network for an EPR4 magnetic recording system. A powerful serially concatenated architecture is considered, consisting of a simple outer code, an interleaver with reasonable size and a rate 1 EPR4 channel as inner code. The analog chip design is based on analog 0.18μm CMOS technology. Simulation results for both digital and analog implementat...

Analog synthesizers continue to be used by many musicians because of their distinctive timbres, intuitive real-time control and flexible patching. There has been recent interest in simulating the analog signal chain with digital techniques. However, a literal time-domain translation of analog VCOs and VCFs is surprisingly challenging. This paper presents a new strategy for digital simulation ba...
