This slide compares the single-ended and differential signal chain performance in a real-world example of the receiver end of a communications system. The first example is the single-ended approach which begins with a single-ended IF driver amplifier, followed by a single-ended anti-aliasing filter and is then converted to a differential signal by a transformer at the input to the ADC. Note that in many cases, the single-ended approach is considered the passive approach because the transformer is used to translate the signal to the differential ADC. The differential example begins with a differential signal at the output of a transformer, a differential ADC driver amplifier, followed by a differential anti-aliasing filter, and the input to the ADC. The differential approach is called active because the amplifier may be used to make the conversion. The performance metrics of each component are listed, however the following slide uses signal chain performance tables with these same metrics to help analyze the cascaded system performance and compare the single-ended and differential approaches.
