Abstract

em uma modalidade, um circuito compreende uma bomba de carga. um circuito de controle de ganho é configurado para detectar uma tensão de entrada e gerar um sinal de controle de ganho para mudar um ganho da bomba de carga para manter a tensão de saída da bomba de carga em uma faixa de tensão. um conversor de tensão para frequência é configurado para detectar a tensão de entrada e mudar uma frequência de um sinal de controle de frequência aplicado à bomba de carga com base na tensão de entrada detectada para manter a frequência em uma faixa de frequência de modo que a tensão de saída da bomba de carga seja mantida na faixa de tensão.
