A​ breakthrough in fully digital ADCs with sampling rates above GHz

Time: Jul 10, 2023

The School of Microelectronics has made important progress in the direction of high-speed analog-to-digital conversion chips (ADCs).


In the field of integrated circuit design, the international top Journal JSSC (IEEE Journal of Solid-State Circuits) published the title "A 0.004-mm2 3.65-mW 7-bit 2-GS/s Single-Channel. GRO-Based Time-Domain ADC Incorporating Dead-Zone Elimination and On-Chip Folding-Offset Calibration in 28-nm  The latest research results of CMOS.


This research uses a new time domain conversion architecture to achieve the world's top ADC chip with high robustness, high single-channel conversion rate and high energy efficiency.
