Title: High-speed digital logic circuit for sar_adc, and sampling adjustment method
Inventor: XU DAIGUO
IPC: H03M1/38
Filed: 2020-01-07
Abstract: A high-speed digital logic circuit for a SAR_ADC, and a sampling adjustment method. The digital logic circuit comprises: a comparator and a logic control unit operating in parallel with each other; and a capacitor array DAC. The comparator and the logic control unit are simultaneously triggered by a clock signal, such that the comparator outputs a valid comparison result Dp/Dn, and the logic control unit outputs a corresponding rising edge signal, wherein delays are matched so as to allow the rising edge signal to be outputted slightly later than the Dp/Dn outputted by the comparator, and the Dp/Dn is then captured by the corresponding rising edge signal, thereby creating a capacitor array. The circuit and the sampling adjustment method help remedy a defect in conventional parallel-mode digital logic, in which a digital logic window captures an invalid output result of the comparator, which results in an improper settling of a capacitor array. Moreover, the invention can maximize sampling times of SAR_ADCs when asynchronous logic is employed.
