Abstract :
We propose a novel approach for analog to digital conversion in communication systems whereby the signal is quantized using three different ADCs with three different phases. We compare the performance of the proposed and the conventional schemes in terms of the mean square error resulting from the quantization versus the overall power consumption for the ADCs. Our results show that by providing additional design points the proposed approach allows us to avoid over designing the ADCs to achieve the required level of signal fidelity and consequently results in significant savings in power consumption.
