Abstract

trata-se de um circuito acionador para transmitir dados seriais em um enlace de comunicação que combina acionadores de modo de tensão e corrente. o circuito acionador usa um acionador de modo de tensão como o acionador de saída principal. um ou mais acionadores de modo de corrente auxiliares são conectados em paralelo ao acionador de modo de tensão para ajustar o sinal de saída injetando-se correntes nas saídas. o acionador de modo de tensão fornece a maior parte do acionamento de saída. logo, o circuito acionador de saída pode proporcionar benefícios de eficiência de energia associados a acionadores de modo de tensão. os acionadores de modo de corrente podem proporcionar, por exemplo, pré-ênfase, ajuste de nível, compensação de distorção, e outas modificações do sinal de saídas. logo, o circuito acionador também pode proporcionar as capacidades de ajuste de sinal associadas aos acionadores de modo de corrente.
