Loren Siebert @ ti.com discuss about how to interface signals that have a reference voltage that isn’t 0V while preserving the DC information. Many signal paths are direct current (DC)-coupled, and this can lead to challenges when different portions of the signal path require different operating conditions. Many portions of a signal path are ground-referenced, […]
