Simultaneous bi-directional transceiver
A simultaneous bi-directional (SBD) transceiver includes a first, second, third and fourth differential amplifiers, where the third differential amplifier responds to signals input through data transmission channels, and the fourth differential amplifier responds to output signals derived from the first differential amplifier. The first and second differential amplifiers are fully differential amplifiers. A size of a constant current source associated with the second differential amplifier is n (n>1) times that of a constant current source associated with the first differential amplifier. A size of a constant current source associated with the third differential amplifier is m (m>1) times that of a constant current source associated with the fourth differential amplifier.
