Abstract
A series capacitive component for use in signal processing applications such as analog-to-digital (A/D) converters, switched capacitor circuits and the like that require matched capacitors is presented. A series capacitive component consists of multiple capacitors connected in series. By utilizing series capacitive components in integrated circuits, significantly lower loads are provided for the same resulting capacitor mismatch range as previous solutions. Additionally, for the same load and noise, using series capacitive components provides a substantially reduced match over previous solutions. Thus a circuit designer has more flexibility when making tradeoffs between circuit area and capacitor mismatch and therefore manufacturing yields.
