Abstract

CIRCUITO DE RECEBIMENTO DE DADOS COM ESPELHO DE CORRENTE E FATIADOR DE DADOS. Um circuito de recebimento de dados é capaz de receber adequadamente sinais modulados por corrente possuindo uma ampla faixa de freqüências. De acordo com uma modalidade ilustrativa, o circuito de recebimento de dados inclui um espelho de corrente (20) que opera para receber um sinal modulado por corrente de um dispositivo externo (10) e para converter o sinal modulado por corrente em um sinal de voltagem. Um fatiador de dados (30) opera para gerar dados digitais que respondem ao sinal de voltagem.
