Reference voltage circuitry for use in switched-capacitor applications |
摘要 |
Circuitry for selectively sampling a reference voltage with a capacitor 403 includes a first switch 505a for selectively coupling capacitor 403 to a source of a first reference signal during a first operating phase and a second switch 505b for selectively coupling capacitor 403 to a source of a second reference signal during a second operating phase.
