This work presents a CMOS four quadrant analog multiplier architecture for application as the synapse element in analog cellular neural networks. The circuit has voltage-mode inputs and a current-mode output and includes a signal application method that ...

Hyperspectral images (HSIs) have been used in civil and military scenarios for ground recognition, urban development management, rare minerals identification, and diverse other purposes. However, HSIs have a significant volume of information and require ...

Automatic License Plate Recognition (ALPR) systems are used to identify a vehicle from an image that contains its plate. These systems have applications in a wide range of areas, such as toll payment, border control, and traffic surveillance. ALPR ...

This paper proposes an adaptive pulse generator using Pulse Amplitude Modulation (PAM). The circuit was implemented with eight Pulse Generator Units (PGUs) to produce up to eight monocycles per pulse. The number of monocycles per pulse is inversely ...

During the last decades we have witnessed the performance improvement and the aggressive growth of the complexity of integrated circuits (ICs). The progressive size reduction of transistors in recent technological nodes has allowed IC designers to ...

In this paper, a hardware design based on the field programmable gate array (FPGA) to implement a linear regression algorithm is presented. The arithmetic operations were optimized by applying a fixed-point number representation for all hardware based ...

Nowadays, the development of systems based on Networks-on-Chip (NoCs) brings big challenges to the designers due to problems of scalability, such as efficient Mapping and Placement, which are NP-hard problems. Several solutions have been proposed to ...

Image sensors dedicated for the applications of the Earth observation require medium-speed and high-resolution analog-to-digital converters (ADCs). For that purpose, an incremental sigma-delta analog-to-digital converter (IΣΔ ADC) has been designed. ...
