We present an analogue VLSI circuit that performs morphological image processing operations on the focal plane. The circuit has been fabricated using a standard digital CMOS process. We exploit the parallelism of morphological image processing operations by using the massively parallel architecture of analogue VLSI arrays, achieving both high-speed and low-power computation [1]. The analogue ci...

Local long-term adaptation is a well-known feature of the synaptic junctions in nerve tissue. Neuroscientists have demonstrated that biology uses local adaptation both to tune the performance of neural circuits and for long-term learning. Many researchers believe it is key to the intelligent behavior and the efficiency of biological organizms. Although engineers use adaptation in feedback circu...

A new smart-sensor VLSI circuit intended for focal-plane processing of grey-scale images is presented. The architecture is based on a fine-grain software-programmable SIMD array. Processing elements, integrated within each pixel of the imager, are implemented utilising a switched-current analogue microprocessor concept. In a 0.6μm CMOS process the cell size is equal to 98.6μm×98.6μm. A prototyp...

Accurately accounting for three dimensional geometry and distributed RC eeects in on-chip interconnect is important for predicting crosstalk in memory cells, analog circuits, and regions of congested routing in digital circuits. In this paper we describe a multipole-accelerated, mixed surface-volume formulation and a preconditioned model-order reduction algorithm for distributed RC, or electroq...

In these days, semiconductor products are integrated within a same die with more complex function components in small scale. It makes possible the emergence of very tiny equipments like hearing aid device, human implant chip, RFID and so on. But, the battery size of mentioned systems will give us obstacle to shrink more. Low-voltage low-power circuit technique will be more valuable to reduce th...

A simple analog circuit is presented which can play a neuron role in static-model-based neural networks implemented in the form of an integrated circuit. Operating in a transresistance mode it is suited to cooperate with transconductance synapses. As a result, its input signal is a current which is a sum of currents coming from the synapses. Summation of the currents is realized in a node at th...

Analog circuits form an important part in integrated circuits and in particular in ASICs (Application Specific Integrated Circuits). However, due to the high complexity, design of this part has become a bottle-neck in the design flow (Gielen, 2007; Rutenbar et al., 2007). To overcome this problem and to guaranty that the analog part can be designed in reasonable time even for future technologie...

The analysis of the analog circuits such as CMOS amplifier pair, Schmitt trigger circuit and op...
