Title:
雑音除去技術を使用したMIMOのΔΣアナログ/デジタル変換回路
Document Type and Number:
Japanese Patent JP5519080
Kind Code:
B2
Abstract:
A multi-input-multi-output-system (MIMO) is provided that includes a first input signal and a second input signal. A plurality of analog-to-digital converter (ADC) cell structures receive as input a combination of the first input signal and the second input signal as well as a combination of quantization noise signals from the respective other ADC cell structures of the plurality of ADC cell structures. The ADC cell structures generate a plurality of first output signals and the noise quantization signals. A plurality of adder modules receive the first output signals and performing either addition or subtraction on a selected combination of the first output signals, the adder modules generate a plurality of second output signals. A plurality of division modules receive the second output signals and perform a division operation on the second output signals by a predetermined factor. The division modules generate a plurality of final output signals of the MIMO.
