Dynamic error compensation in track-and-hold circuits |
摘要 |
Circuits and methods are provided that compensate for dynamic errors caused by voltage drops across a switch coupled in series with a capacitor in an electrical circuit such as a track-and-hold circuit. In such circuits, the capacitor should provide the same voltage as a signal coupled to the switch, but does not because of the switch voltage drop. The switch can be, for example, a MOSFET or more particularly a CMOS device. Dynamic errors are compensated for by measuring the voltage drop across the switch and then effectively adding the measured voltage drop to a voltage provided by the capacitor.
