In an embodiment, the passive buffer circuit includes buffer elements connected between input terminals and output terminals that are connected to input terminals of a communication component circuit with a plurality of input transistors. Each of the buffer elements provides a first path with a resistor and a second path with a series-connected capacitor and inductor. The passive buffer circuit further includes current sources connected between the output terminals and at least one fixed voltage and a feedback loop from the input transistors to the current sources to control direct current (DC) voltage at each of the input terminals of the communication component circuit. The feedback loop includes an error amplifier that controls the current sources based on voltages on the input transistors with respect to a reference voltage."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Wideband passive buffer with DC level shift for wired data communication","description":"Embodiments of a passive buffer circuit and a wideband communication circuit that uses the passive buffer circuit are disclosed.
