Patent ID: 8301093

Claim:
A receiver circuit connectable to a first and a second transmission lines which transmit information by using currents, the receiver circuit comprising: a first current source and a second current source; a first conversion circuit configured to convert a current which flows the first conversion circuit to a first voltage; a second conversion circuit configured to convert a current which flows the second conversion circuit to a second voltage; a first transistor whose source is coupled to the first current source and connectable to the first transmission line, and whose drain is coupled to the first conversion section, the first transistor being configured to receive, at the source thereof, a current supplied from the first current source; a second transistor whose source is coupled to the second current source and connectable to the second transmission line, and whose drain is coupled to the second conversion section, the second transistor being configured to receive, at the source thereof, a current supplied from the second current source; a data recovery circuit configured to receive the first voltage converted by the first conversion circuit and the second voltage converted by the second conversion circuit; and a clock recovery circuit configured to receive the first voltage converted by the first conversion circuit and the second voltage converted by the second conversion circuit, wherein: the gate of the first transistor is coupled to the drain of the second transistor, the drain of the first transistor is coupled to the gate of the second transistor, the currents which flow through the first and the second transmission lines transmit a data signal and a clock which are superimposed thereon, a frequency of the clock is one half of a transmission frequency of the data signal, the data recovery circuit is configured to recover the transmitted data signal according to the first and second voltages, and the clock recovery circuit is configured to recover the transmitted clock according to the first and second voltages.
