Patent number: 11374588Abstract: An analog to digital converter temperature compensation system comprising a comparator configured to compare an analog input signal to a compensated feedback signal and generate a comparator output. A SAR module processes the comparator output to generate a digital signal. A digital to analog converter, biased by a biasing signal having temperature change induced error, is configured to convert the digital signal to a feedback signal and a detector is configured to detect a signal that is proportional to temperature. A look-up table is configured to receive and convert the signal that is proportional to temperature to a compensation signal such that the compensation signal compensates for the temperature change induced error in the biasing signal. A summing node combines the feedback signal with the compensation signal to create a compensated feedback signal.Type: GrantFiled: April 21, 2021Date of Patent: June 28, 2022Assignee: MACOM Technology Solutions Holdings, Inc.Inventors: Chi Mo, Donghai Wang, Quazi Ikram, Ahmad Yazdi
