摘要：

Disclosed examples include pipeline ADC, balancing circuits and methods to balance a load of a reference circuit to reduce non-linearity and settling effects for a reference voltage signal, in which balancing capacitors are connected to a voltage source in a pipeline stage ADC sample time period to precharge the balancing capacitors using a voltage above the reference voltage, and a selected set of the precharged balancing capacitors is connected to provide charge to the output of the reference circuit during the second time period.
