Abstract :
A high speed CMOS current-mode interpolating flash analog-to-digital converter capable is proposed. The design uses generic cells to generate all current comparator inputs. The proposed interpolation technique reduces the transistor count and power consumption of a pure flash implementation while improving SNR, SFDR, and DNL. Five-bit interpolating flash and pure flash designs were implemented in 0.5 mm CMOS to compare performance characteristics.
