Pre-Charge Systems and Methods for ADC Input Sampling |
摘要 |
The invention provides methods and systems useful for quickly and accurately sampling a switched capacitive load. Systems are disclosed in which the methods are implemented using an operational amplifier operably coupled to a pre-charge capacitor for storing an input charge. A sampling capacitor is also coupled to the operational amplifier and to the pre-charge capacitor for receiving and holding the input charge. The system is so configured for a coarse sampling phase and a fine sampling phase the to ensure that the sampling capacitor settles quickly to provides an output.
