Abstract
Methods, apparatus, systems and articles of manufacture are disclosed to control switching of a sampling circuit. An example apparatus includes an offset window detector to determine whether a first voltage meets a first threshold of a target input voltage; a settling time detector coupled to the offset window detector, the settling time detector to determine whether a second voltage meets a second threshold, the second voltage dependent on a delay of the settling time detector, the delay of the settling time detector to track a time response of a scaling amplifier; and a sample acquisition controller coupled to the offset window detector and the settling time detector, the sample acquisition controller operable to cause a reference voltage to be sampled, in response to the first threshold and the second threshold being met.
