<p>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 transition levels.</p> |
