Track and hold circuits for high speed ADCS
A dither capacitor, separate from the capacitor sampling the input signal, can be used to inject the additive dither in the switched-capacitor network of the track and hold circuit. This implementation can be referred to as a split-capacitor dither injection. The dither capacitor can be connected to...

| Zusammenfassung: | A dither capacitor, separate from the capacitor sampling the input signal, can be used to inject the additive dither in the switched-capacitor network of the track and hold circuit. This implementation can be referred to as a split-capacitor dither injection. The dither capacitor can be connected to a summing node of the switched-capacitor network. Using a separate capacitor allows the dither to be isolated from the capacitor that is sampling the input signal and avoids kick-back errors. |
