Abstract
An analog-to-digital converter 10 employs a series of comparators 12, 14, 16 and 18. Each comparator includes at least one inverter consisting of a CMOS transistor pair including a P-channel transistor 22 and N-channel transistor 24. The threshold levels of the transistors 22, 24 are modified using focused ion beam implantation techniques to provide the comparators with monotonically increasing transistion levels.
