摘要： A flash analog-to-digital converter comprises a resistive string powered by a reference voltage source for providing a set of equidistant reference voltages and a set of comparators for comparing the analog input signal with the reference voltages. A set of switches are arranged and controlled to perform an algorithm for mitigating the influence of mismatches between the components. The switches are arranged between the reference voltage source and the resistive string so that switches in the reference inputs to the comparators are avoided. The resistive string is preferably circular. The converter can handle differential signals.
