Samenvatting

A 5bit 1GS/s 0.05mm2 4× time-interleaved asynchronous digital slope ADC in 90nm CMOS for IR UWB radio is presented. New delay cells are introduced to double the speed over prior art, yielding the 250MS/s single-channel slope converter. A self-disabled comparator eliminates static leakage and consumes only 0.25pJ/conversion. A single calibration circuit corrects both offset errors and mismatches in the new delay cells, achieving an ENOB of 4.85bit with 1.5GHz ERBW. This ADC consumes 2.7mW at a 1V supply, enabling a FoM of 93fJ/conversion-step. At 0.8V, it can work at 0.5GS/s. Even compared to the state-of-the-art of well-established architectures, it achieves similar power-efficiency.
