<p>A dead-zone comparator includes first and second component voltage comparators used respectively to compare an input signal to a high reference level and to a low reference level, which reference levels may be programmable. A bistable is set by the output signal of one comparator and reset by the output signal of the other. These SET and RESET signals are opposite polarity currents, one of which is more severely constrained in value than the other, and are applied via a common SET-RESET buss to the bistable.</p> |
