Title:
ＡＤ変換装置および信号処理システム
Document Type and Number:
Japanese Patent JP5733027
Kind Code:
B2
Abstract:
An analog-to-digital conversion apparatus includes: a first analog-to-digital converter configured to convert an input analog signal into a digital signal; a second analog-to-digital converter configured to convert an analog signal generated by multiplying the input analog signal by alpha times with a coefficient alpha into a digital signal; a first non-linear compensation part configured to compensate a non-linear distortion of a first output signal of the first analog-to-digital converter; a second non-linear compensation part configured to compensate a non-linear distortion of a second output signal of the second analog-to-digital converter; and a non-linear detection part configured to estimate how much the non-linear distortions of the first and second analog-to-digital converters are compensated by the first and second non-linear compensation parts depending on first and second signals by the first and second non-linear compensation parts.
