ABSTRACT:
A method of operating a charge redistribution analog-to-digital converter. The method includes sampling a first voltage with a capacitive network, and then switching the plate of one of the capacitors in the network from a supply voltage node to a reference voltage node. After switching, a second voltage is sampled, and a quantity of charge stored in the capacitive network, which quantity results from both of the sampling steps, is tested. In another general aspect, a method of converting an analog voltage to a digital value, which includes sampling a charge related to the analog voltage, and precharging and charging capacitors in an array. The charge sampled in the step of sampling is then tested against a charge stored in the capacitors in the array.
