A reconfigurable 60GHz subsampling receiver architecture with embedded channel filtering

This paper presents a 60GHz heterodyne receiver architecture with IF sub-sampling. A particular arrangement of the frequency plan allows anti-alias filtering by the charge-domain subsampler. Down-conversion, channel filtering and IQ demodulation are merged into a unique operator without any extra cost in terms of area and power consumption. The proposed architecture is able to receive up to 4 bonded channels and complies with the requirements of the standards for 60GHz wireless communications. The result of this study shows that subsampling is a good candidate for low power and configurable receivers for mmW wireless communications.
