Future mm-Wave wireless links with datarates of 20Gbps and more will result in prohibitive power consumption at the front end of the DSPs. The use of analog or mixed-signal baseband processing, however, can significantly relax the receiver power budget. The most critical block for such a baseband is the decision feedback equalizer, that compensates for the line-of-sight multi-path components and demodulates the signal. In this paper we present a complex DFE capable of handling 16QAM data at 9GHz RF bandwidth, aggregating all 4 channels of the 60GHz IEEE802.11ad band and resulting in a maximum datarate of 36Gbps. It is able to compensate for 0.7× cursor amplitude of inter-symbol interference spread over 5 complex taps, while the minimum input SNR is 26dB. It consumes 138mW from a 0.9V supply, achieving 3.8mW/Gbps power efficiency including clock distribution.
