Abstract
A comparator presents a linear load to input signals when providing a comparison output of two input signals. The comparator contains a transistor configured in a source/emitter follower configuration, and operates in the saturation region for substantially the entire range of strengths of the input signals. As a result, the comparator presents a substantially constant load to the input signals. When incorporated in circuits such as a pipeline ADC, the comparator may substantially eliminate errors due to non-linear loads.
