Abstract: A code-division multiplexing (CDM) system utilized in multi-channel (MC) front-end integrated circuits to significantly reduce the power consumption of such systems. The CDM system extends data compression advantages to uncorrelated and weakly correlated MC signals through the introduction of a new Multi-Channel Signal Binning and Multiplexing (MCSBM) method and architecture. The method achieves significant reductions in power consumption in comparison to a conventional time-division multiplexing quantizer, while adding only a modest amount of overhead and complexity. Systems and methods permit architects to fabricate MC integrated circuits with ultra low power consumption and small chip area. Another embodiment relates to the system's compressor organizing samples of the input signal in such a way that the downstream analog-to-digital converter quantizes the higher variance samples with a higher resolution compared to the resolution it uses to quantize other samples with lower variance.
