Este artigo propõe uma técnica para reduzir a dispersão de capacitância em filtros de capacitor chaveado (SC). A técnica proposta é baseada em uma distribuição simples de carga e transferência parcial de carga que é aplicável a diversas topologias de integrador. Um exemplo de implementação em uma topologia de integrador existente e um exemplo de projeto de um filtro passa-baixa SC de 2ª ordem são fornecidos para demonstrar o desempenho da técnica proposta. Um exemplo de projeto de um filtro SC mostra que o filtro projetado usando a técnica proposta possui aproximadamente 23% menos capacitância total do que o filtro passa-baixa SC com técnica convencional de redução de espalhamento de capacitância.

Abstract: This paper proposes a technique to reduce the capacitance spread in switched-capacitor (SC) filters. The proposed technique is based on a simple charge distribution and partial charge transfer which is applicable to various integrator topologies. An implementation example on an existing integrator topology and a design example of a 2nd-order SC low-pass filter are given to demonstrate the performance of the proposed technique. A design example of an SC filter show that the filter designed using the proposed technique has an approximately 23% less total capacitance than the one of SC low-pass filter with conventional capacitance spread reduction technique.
