A high input impedance circuit to convert a single-ended (SE) voltage to its differential counterpart is proposed. It allows setting the common-mode (CM) output voltage to a reference voltage vR, while providing gain and a balanced output. The circui

A simple encoding method for Sigma-Delta ADC based biopotential acquisition systems

Autor: Enrique Mario Spinelli, Federico Nicolás Guerrero

Sigma Delta analogue-to-digital converters allow acquiring the full dynamic range of biomedical signals at the electrodes, resulting in less complex hardware and increased measurement robustness. However, the increased data size per sample (typically

Analysis and Simple Circuit Design of Double Differential EMG Active Electrode

Autor: Enrique Mario Spinelli, Marcelo Alejandro Haberman, Federico Nicolás Guerrero

Publikováno v: IEEE transactions on biomedical circuits and systems. 10(3)

In this paper we present an analysis of the voltage amplifier needed for double differential (DD) sEMG measurements and a novel, very simple circuit for implementing DD active electrodes. The three-input amplifier that standalone DD active electrodes

Autor: Federico Nicolás Guerrero, S. A. González, Enrique Mario Spinelli

Publikováno v: IFMBE Proceedings ISBN: 9783319131160

This work presents a neuro-muscular stimulator (NMS) specially designed for autonomous neuroprosthesis, and focused on the optimization of the battery energy consumption. The main feature of the proposed NMS is that it does not use an auxiliary high
