Patent number: 10735008Abstract: A comparator offset voltage self-correction circuit is disclosed. A comparator offset voltage which is caused by the semiconductor process parameter randomness also has randomness. Due to the randomness of the comparator offset voltage, a reference voltage of a parallel comparator in a parallel-conversion-type analog-to-digital converter is uncertain. If the comparator offset voltage is large, the parallel-conversion-type analog-to-digital converter may even have a functional error. The comparator offset voltage self-correction circuit provided in the present invention can correct a random offset voltage of a comparator to meet requirements.Type: GrantFiled: June 27, 2016Date of Patent: August 4, 2020Assignee: CHINA ELECTRONIC TECHNOLOGY CORPORATION, 24TH RESEARCH INSTITUTEInventors: Rong-Bin Hu, Yong-Lu Wang, Gang-Yi Hu, He-Quan Jiang, Zheng-Ping Zhang, Guang-Bing Chen, Dong-Bing Fu, Yu-Xin Wang, Lei Zhang, Rong-Ke Ye, Can Zhu, Yu-Han Gao
