Line driver for digital signal transmission

A pseudo-differential line driver for amplifying a differential total input current, comprising a first and a second input current portion, into a differential total output current, a first and a second output current portion, with a first and a second line driver wherein each line driver comprises

• a drive amplifier, a voltage-controlled output current source, a current/voltage converter, a voltage/current converter, a first node, a second node and a third node, wherein
• the input current can be injected into the first node,
• a first amplifier input on the drive amplifier is coupled to the first node and a second amplifier input on the drive amplifier essentially has a reference voltage applied to it,
• the current/voltage converter, which is connected between the first node and the second node, is designed such that it converts a first current, which feeds the current/voltage converter from the first node, into a voltage which is present on the second node,
• the voltage/current converter, which is connected to the second node, is designed such that it converts the voltage present on the second node into a second current and supplies the second current to a current sink,
• the voltage-controlled output current source can be controlled by the drive amplifier, and a current-carrying path in the voltage-controlled output current source is connected between the second node and the third node, and
• the output current can be output from the third node, and wherein
• the first node of the first line driver can have the first input current portion injected into it and the first node of the second line driver can have the second input current portion injected into it,
• the third node of the first line driver can output the first output current portion and the third node of the second line driver can output the second output current portion, and
• the reference voltages of the first and second line drivers have the same value.
