Abstract (en)

[origin: WO0069070A1] A circuit arrangement in accordance with the invention has a first (1) and a second (2) supply terminal for receiving supply voltages (Vdd and Vss, respectively). The circuit arrangement further has an input terminal (3) for receiving an input signal (Si) and has an output terminal (4) for supplying an output signal (So). The circuit arrangement further includes level shifting means for effecting a shift in d.c. level of the output signal (So) with respect to the input signal (Si). The level shifting means include a current source (5) and resistive means (6). The output terminal (4) is connected to an output of the current source (5). The output terminal (4) is also connected to the input terminal (3) via resistive means (6). The invention also relates to a device for reading/writing an optical record carrier, including such a circuit arrangement.
