This paper presents a non-uniform sampling analog-to-digital converter (ADC) architecture using an adaptive level-crossing technique. The architecture can be dynamically configured through three parameters that allow the user to match the ADC to the signal to be acquired or to application constraints. When applied to sparse signals, this architecture outperforms uniform sampling architectures. In...
This article proposes an arbitrary waveform generator based on the Berlekamp-Massey Algorithm (BMA) modified to operate in the Real field. The main application for the proposed generator is in integrated mixed circuits test, particularly analog-to-digital converters. Simulations of the proposed generator were performed using MatLab® software. Results for different waveforms (input sequence) generated...
In this article, we examine different architectures of analog-to-digital converters (ADCs) and propose a flexible architecture based on sampling by crossing levels and adaptive quantization step, aiming at reducing the energy required to convert and process specific signals. The proposed architecture has parameters which can be configured by the user, in order to adapt the conversion process to the...
