Abstract
"CIRCUITO DE REGULAGEM DE FREQuêNCIA". A presente invenção refere-se a um circuito de regulagem de freq³ência para o suprimento de clock em função do consumo de corrente de uma disposição de circuito. O circuito de regulagem de freq³ência possui uma disposição de medida de corrente (2) instantânea da disposição do circuito (1), um circuito de suprimento de clock comandável (4) conectável a uma entrada de clock da disposição de circuito (1), e uma disposição de controle (3) para o controle do circuito de suprimento de clock (4) com base na medida da corrente recebida, onde um aumento de corrente recebida pela disposição de circuito (1) resulta em uma redução da freq³ência de clock na saída (6) do circuito de suprimento de clock (4). Por intermédio deste circuito fica assegurada a não ultrapassagem de uma corrente máxima permissível, entretanto possibilita uma potência máxima do circuito através de uma freq³ência de clock máxima.
