METHODS AND DEVICES FOR ANALOG-TO-DIGITAL CONVERSION

摘要

Analog-to-digital converter arrangements and corresponding methods are provided, wherein a reduction signal is subtracted from an analog input signal if a signal level of the input signal exceeds a threshold value.

主权项

1. An analog-to-digital converter arrangement, comprising:
an analog signal input configured to receive an analog input signal, a subtractor, wherein a positive input of the subtractor is coupled to the analog signal input, an amplifier, wherein an input of the amplifier is coupled to an output of the subtractor, an analog-to-digital converter, wherein an input of the analog-to-digital converter is coupled to an output of the amplifier, and a signal correction device comprising a bit splitter arrangement, wherein an input of the bit splitter arrangement is coupled to an output of the analog-to-digital converter, wherein the bit splitter arrangement is configured to divide a supplied digital signal into a first signal with high-value bits and a second signal with low-value bits, and wherein the signal correction device is configured to form a reduction signal on the basis of the first signal and to supply the reduction signal to a negative input of the subtractor.
