Abstract(in English) | We proposed a novel single slope ADC using an interpolative TDC (ITDC) to develop a high-speed and low-power ADC, and reported that the proposed ADC demonstrated a high sampling frequency of 500 MHz. It is predicted that the accuracy of the ITDC is seriously degraded due to the process variability because its resolution is a half of that of the conventional TDC. Therefore, the influence of the process variability on the accuracy of the ITDC was investigated. As a result, we found that the influence of the comparator offset was negligible, and the conversion gain of the ADC considerably changed due to the delay time change of the ring oscillator, and the conversion error increased due to the timing mismatch in the sampling switch. Moreover, it was shown that the conversion error generated by above-mentioned phenomena could be compensated for by adjustment of the ramp speed and threshold voltage of the comparator. |
