Patent number: 11070225Abstract: An analog to digital converter (ADC) is disclosed. The ADC includes a DAC which generates a first signal based on an analog input and a digital input word, and a comparator which generates a comparator output having a value corresponding with a sign of a difference between first and second signals. During a first time period, the second signal is equal to a reference signal, the first signal is equal to an analog input, and the comparator generates a first comparator output. During a second time period, the second signal is equal to the reference signal, the first signal is equal to a the analog input plus a predetermined signal, and the comparator generates a second comparator output. A SAR logic circuit generates the digital input word for the DAC based on the first and second comparator outputs.Type: GrantFiled: June 30, 2020Date of Patent: July 20, 2021Assignee: SHENZHEN GOODIX TECHNOLOGY CO., LTD.Inventors: Mohamed Aboudina, Ali Farid, Ahmed Emira, Hassan Elwan
