Abstract

"CIRCUITO ELéTRICO, UNIDADE MOSTRADORA, E, PROCESSO PARA ELIMINAR UMA INFLUêNCIA DE UMA QUEDA DE TENSãO (DV) AO LONGO DE UM CONDUTOR ELéTRICO". A invenção resolve um problema de compensar uma queda de tensão não desejada ao longo de um condutor de corrente CC (10) conectado a um circuito integrado (20). O inventivo aparelho compreende um amplificador diferencial (106) conectado entre uma fonte de tensão (105) e o condutor (10) do circuito integrado (20) que é prejudicado pela queda de tensão. Um terminal de entrada (103) do amplificador (106) é conectado ao condutor de fonte (105) e um terminal de saída (109) do amplificador (106) é conectado ao condutor (10). A rede de realimentaçãqo (51) é conectada entre outro terminal de entrada (104) do amplificador (106) e o circuito integrado (20). Uma diferença de potencial entre os dois terminais de entrada (103, 104) sobre o amplificador (106) conduzirá ao amplificador 106 ajustar um potencial sobre o terminal de saída (109) até que a queda de tensão não desejada ao longo do condutor (10) seja compensada.
