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.

摘要： During successive approximation analog to digital conversion a series of successive digital reference values is selected that converges towards a digital representation of an analog input signal. An analog reference signal is generated dependent on the successive digital reference values and compared to the analog input signal. The digital reference values are selected dependent on comparison results. In the selection of the digital reference values successive steps between digital reference values are each selected dependent on values of the comparator result from a plurality of preceding recursion cycles. The comparison results define a series of successively narrower ranges of digital values that contain a digital representation of the analog input signal. Use of a plurality of comparator results for selecting the steps in the digital reference values makes it possible to reduce uncertainty about whether the comparison result has settled. This in turn makes it possible to reduce the sizes of the successive ranges, which speeds up convergence.

摘要： A sampling circuit for sampling a signal is disclosed. The sampling circuit comprises a plurality of sampling channels adapted to sample the signal in time-multiplexed fashion, each sampling channel comprising a respective track-and-hold circuit connected to a respective analogue to digital converter via a respective output switch. The output switch of each channel opens for a tracking time period when the track-and-hold circuit is in a tracking mode for sampling the signal, and closes for a holding time period when the track-and- hold circuit is in a holding mode for outputting the sampled signal. The holding time period comprises a settling time period that is at least as long as the tracking time period. The settling time period is used by the track-and-hold circuit to charge an input capacitance of the analogue to digital converter to a voltage according to the sampled signal.
