ABSTRACT:
Disclosed is an AD converter including: a first conversion stage including a quantizing part to generate m parallel pieces of quantized signals from m pieces of input analog signals representing n-dimensional vectors (n<m<2n), a decoding part to generate m pieces of decoded analog signals from the m parallel pieces of quantized signals, and a residual amplifying part to output m pieces of amplified residual signals by multiplying respective differences between each of the m pieces of analog signals and each of the m pieces of decoded analog signals; a second conversion stage including a quantizing part to generate m parallel pieces of quantized signals from the m pieces of amplified residual signals; and a synthesizing part to generate m parallel pieces of digital signals by synthesizing each of the quantized signals in the first conversion stage and in the second conversion stage at each parallel position.
