Abstract

são fornecidos circuitos de modulação de voltagem adaptativa para ajustar a voltagem de alimentação para reduzir as quedas de voltagem de alimentação e minimizar o consumo de energia. em um aspecto um circuito de modulação de voltagem adaptativa detecta uma queda de voltagem de alimentação pela detecção quando uma voltagem de alimentação cai abaixo de uma voltagem de limite de queda, e ajusta um sinal de relógio fornecido a um circuito de carga em resposta a uma queda de voltagem de alimentação. o circuito de modulação de voltagem adaptativa mantém uma contagem do número de ciclos de sinal de relógio durante o qual a voltagem de alimentação está abaixo da voltagem de limite de queda. o circuito de modulação de voltagem adaptativa aumenta a voltagem de alimentação em resposta à contagem que excede um valor limite superior, e diminui a voltagem de alimentação em resposta à contagem menor do que um valor limite inferior em uma extremidade de um período definido. o circuito de modulação de voltagem adaptativa pode reduzir o tempo em que um circuito de carga opera com frequência reduzida, ao mesmo tempo em que minimiza o consumo de energia.
