Abstract

Patente de Invenção: "CONVERSOR ATIVO DE DIFERENCIAL PARA SINGLE-ENDED". Muitas aplicações exigem a conversão de um sinal de corrente diferencial em um sinal single-ended. As deficiências enfrentadas com as abordagens existentes incluem eficiência de conversão insatisfatória, largura de banda de onda limitada, e grandes dimensões. O conversor aqui apresentado utiliza dispositivos ativos para obter uma unidade de pequeno porte e alto rendimento tendo uma ampla largura de banda de operação.
