A low voltage differential signal buffering system is provided to minimize non-continuity in impedance by compensating for an input signal difference between a base and a virtual ground terminal of a differential amplifier structure. A low voltage differential signal buffering system includes first and second transistors(Q1,Q2), a node(40), first and second output terminals(34,36), and a comparator(38). The node is virtually grounded through one of the terminals of the first and second transistors. The first and second output terminals are connected to the first and second transistors, respectively. The comparator is parallel-connected between the first transistor and the first output terminal and between the second transistor and the second output terminal. The comparator detects an output signal difference between the first and second output terminals, and compensates for an input signal difference between first and second input terminals, when the output signal difference is detected. |
