Abstract

A circuit for signal voltage transmission within a driver contains, on its primary side, a signal input for a first signal voltage, a current source for a current correlated with the first signal voltage, a connecting line for the current, the connecting line leading from the current source to the secondary side of the driver, and, on the secondary side, a current-voltage converter for converting the current into a second signal voltage correlated with the current, and a signal output for the second signal voltage. On the primary side, the first signal voltage is applied to the signal input, the current source generates a current correlated with the signal voltage, and the current passes to the secondary side via the connecting line. On the secondary side, the current-voltage converter converts the current into the second signal voltage and the second signal voltage is output at the signal output.
