Abstract:
1. A simultaneous bi-directional (SBD) transceiver comprising: a first differential amplifier, comprising; a first pair of input terminals, a first pair of output terminals, and a first constant current source communicating a first current; a second differential amplifier, comprising; a second pair of input terminals, a second pair of output terminals, and a second constant current source communicating a second current twice as large as the first current; a third differential amplifier, comprising; a third pair of input terminals, a third pair of output terminals, and a third constant current source communicating a third current; and a fourth differential amplifier, comprising a fourth pair of input terminals, a fourth pair of output terminals, and a fourth constant current source communicating a fourth current, wherein the third current is twice as large the fourth current, wherein the first pair of input terminals is connected terminal-for-terminal with the second pair of input terminals; wherein the first pair of output terminals is connected terminal-for-terminal with the fourth pair of input terminals; wherein the second pair of output terminals is connected terminal-for terminal with the third pair of input terminals; and, wherein the third pair of output terminals is connected terminal-for terminal with the fourth pair of output terminals.
