Moreover, we discuss two examples of such architectures. In this paper, we describe the operating principle and the digital estimation in more detail and give a more detailed transfer function analysis.
The description in is terse and the performance analysis is rudimentary. In consequence, control-bounded converters can use more general analog filter structures (potentially consuming less power) than delta–sigma converters. Moreover, the reconstruction principle of control-bounded conversion differs from other conversion principles. However, control-bounded conversion stands out by its analog part operating in continuous time (rather than with discrete-time samples), which is reminiscent of continuous-time delta–sigma ( \(\varDelta \Sigma \)) converters. Like several other conversion principles (including pipelined conversion, beta-expansion conversion, and modulo conversion ), control-bounded conversion works by multiple stages of analog amplification with intermediate steps of adding (or subtracting) digitally controlled quantities. Control-bounded analog-to-digital conversion was proposed in, as a simplification of control-aided analog-to-digital conversion proposed in.
