Abstract:
A conversion operation B is performed with respect to a sample value R in an A/D conversion stage 101 to generate a conversion result D3, and a sampling operation A is performed with respect to this conversion result D3 in an A/D conversion stage 103. The conversion operation B is performed with respect to a sample value in an A/D conversion stage 105 to generate a conversion result D4, and the sampling operation A is performed with respect to the conversion result D4 in an A/D conversion stage 107. The conversion operation B is performed with respect to a sample value in an A/D conversion stage 107 to generate a conversion result D5, and the sampling operation A is performed with respect to this conversion result D5 in an A/D conversion stage 101. The conversion operation B is performed with respect to a sample value in the A/D conversion stage 103 to generate a conversion result D6, and the sampling operation A is performed with respect to the conversion result D6 in the A/D conversion stage 105.
