ABSTRACT:
In a summing comparator (10) in which one differential input voltage received by one differential pair (18) is dependent on temperature variations, such as across a resistor (12) with a large temperature coefficient, the dependence on temperature is offset by introducing cancelling temperature dependence in the other differential pairs (14, 16).
