| Zusammenfassung: | A system and apparatus for reducing offset voltages in folding amplifiers is disclosed. In one form, a folding amplifier for use in an analog-to-digital converter is provided. The folding amplifier includes a first current source operable to be coupled to a first differential pair and a second differential pair. The folding amplifier further includes a switching network coupled between the first current source and the first and second differential pairs and operable to enable coupling the first current source to at least one of the first differential pair and the second differential pair. |
