ABSTRACT:
A current mode bus interface system includes a host interface device configured to transmit a reference current and a clock current, and to transmit a data current during a first transfer mode, and to receive a reverse direction data current and compare the reverse direction data current with the reference current to generate a reverse direction data voltage during a second transfer mode; and a client interface device configured to receive the reference current and the clock current and compare the reference current with the clock current to generate a clock voltage, to receive the data current and compare the data current with the reference current to generate a data voltage during the first transfer mode, and to transmit the reverse direction data current through a conducting wire over which the data current is received during the second transfer mode.
