Quantization circuit and method for quantizing an input quantity

摘要

A quantization circuit includes a quantizer configured to provide a quantized sample using an input quantity and an error estimator configured to determine a quantization error of the quantized sample. An error corrector is configured to correct the quantized sample by a correction value depending on the quantization error.
