Abstract

Patente de Invenção: <B>"CHIP DE SENSOR DE IMAGEM E SENSOR DE IMAGEM"<D>. Um chip de sensor de imagem (24) tem uma pluralidade de fototransistores (PHT) para converter luz refletida por um objeto escaneado em sinais de imagem análogos, um registrador de deslocamento (SR) e primeiros transistores de efeito de campo (FET~ 1~) para uma emissão seq³encial dos sinais de imagem em série dos respectivos terminais de saída da pluralidade de fototransistores (PHT), um primeiro atenuador (1) para produzir sinais de imagem emitidos em série pelo registrador de deslocamento (SR) e os primeiros transistores de efeito de campo (FET~ 1~), um amplificador operacional (OP) capaz de amplificar os sinais de imagem a partir de uma pluralidade de fotoransistores (PHT), um segundo atenuador (2) conectado a um terminal de entrada do amplificador de operação (OP), e um terceiro atenuador (3) conectado a um terminal de saída do amplificador de operação (OP).
