Multiple-bit, current mode data bus

摘要

A current mode data communication system is disclosed. The current mode data communication system has a transmitter to simultaneously transmit two digital data bits. The two digital data bits are combined to form a current mode signal. The current mode signal has a first positive current, a second positive current, a first negative current and a first positive current. The current mode signal will be transmitted on a double bit current mode bus. Further the current mode communication system has a receiver coupled to the double bit current mode bus to receive the current mode signal and convert the current mode signal to a unextracted form of the two digital data bits. The output of the receiver is connected to a data extractor circuit extract the two digital data bits for the unextracted form of the two digital data bits.
