Sobre IBD

Neste trabalho, centramo-nos na tecnologia RFID UHF passiva e, mais especificamente, na conceção de uma arquitetura analógica para uma etiqueta RFID UHF passiva, com o objetivo de melhorar a sua distância de funcionamento. Estas etiquetas passivas são constituídas por um chip eletrónico e uma antena e não têm fonte de energia própria. São alimentadas por uma onda electromagnética emitida pelo leitor quando se encontram na zona de leitura definida por uma distância de funcionamento. O principal obstáculo ao alargamento da gama de aplicações da tecnologia RFID a outros domínios é a sua curta distância de funcionamento. Esta distância é inversamente proporcional à potência recebida pela etiqueta, pelo que a redução do consumo de energia levará automaticamente a um aumento da distância de operação, abrindo caminho para novas aplicações RFID. O principal objetivo deste trabalho é, portanto, propor uma solução para este problema, reduzindo o consumo de energia dos vários módulos do chip e melhorando a eficiência do circuito de recuperação de energia.
