Low-swing operation both in the analog and the digital circuitry results in high-speed low power operation. The ADC dissipates 70 mW power from a 1.8 V supply while operating at 5 GHz. Offset averaging is used to minimize the effect of comparator offsets. Simulation results show that offset voltages with 67 mV standard deviation (i.e., 1 LSB) can be tolerated. Static INL and DNL errors are 0.34 LSB and 0.24 LSB respectively, and the ENOB is 3.65 bits. The simulation results of this non-time-interleaved flash ADC demonstrates a significant improvement in terms of power and area compared to those of previously reported ADCs %9 inproceedings
