Abstract
One way to increase the conversion bandwidth of the Delta-Sigma (ΔΣ) A/D converter is to use parallelism. The three main types of parallel ΔΣ A/D converter which are practical for implementation are the time-interleaved, the parallel ΔΣ (ΠΔΣ), and the frequency band decomposition A/D converters. In this paper, it is shown that the operation of all three approaches can be explained using the same underlying theory. This common structure is then used to explore the design tradeoffs among these architectures
