Abstract
This paper presents a SC-FDE/OFDM MMSE equalizer for 60GHz wireless communications in 65nm CMOS process. By applying a 4-parallel signal processing architecture, the 512pt FFT/IFFT processor, the Golay channel estimator, and the MMSE equalizer are all clocked at 1/4 input symbol sampling rate. Occupying a core area of 1.12mm2, the symbol sampling rate at 1V supply is 1.46GS/s. With 16QAM modulation, its throughput is 5.84Gb/s while consuming 124mW in the SC-FDE mode and 88mW in the OFDM mode. With a 1.2V supply, it achieves a symbol sampling rate of 1.76GS/s with a 7Gb/s throughput while consuming 208mW in the SC-FDE mode and 148mW in the OFDM mode.Keywords
