A complete digitally-programmable analogue Fuzzy Logic Controller (FLC) is presented. The design of some new functional blocks and the improvement of others aim towards speed optimisation with a reasonable accuracy, as it is needed in several analogue Signal Processing applications. A nine-rules, two-inputs and one-output prototype was fabricated and(More)
Kohonen maps are self-organizing neural networks that classify and quantify n-dimensional data into a one- or two-dimensional array of neurons. Most applications of Kohonen maps use simulations on conventional computers, eventually coupled to hardware accelerators or dedicated neural computers. The small number of different operations involved in the(More)
This survey of the pros and cons of analog devices presents a 14-neuron test chip and an algorithm for fully interconnected networks. S ince the pioneering work of McCulloch and Pitts in 1943,' many researchers have tried to realize artificial devices that emulate the human brain. The challenge is to obtain a computational power unknown to conventional von(More)
This paper demonstrates that fully-depleted (FD) silicon-on-insulator (SOI) technology offers unique opportunities in the ®eld of low-voltage, low-power CMOS circuits. Beside the well-known reduction of parasitic capacitances due to dielectric isolation, FD SOI MOSFETs indeed exhibit near-ideal body factor, subthreshold slope and current drive. These assets(More)
Abstrud-Hopfield's neural networks show retrieval and speed capabilities that make them good candidates for content-addressable memories (CAM's) in problems such as pattern recognition and optimization. This paper presents a new implementation of a VLSI fully interconnected neural network with only two binary memory points per synapse (the connection(More)
A digitally-programmable analogue Fuzzy Logic Controller (FLC) is presented. Input and output signals are processed in the analog domain whereas the parameters of the controller are stored in a built-in digital memory. Some new functional blocks have been designed whereas others were improved towards the optimisation of the power consumption, the speed and(More)
