Circuit structure for converting digital signals into analog signals has converting and filtering devices with an impedance transfer function

摘要

Converting devices (CD) (10) convert a digital signal (1) into an analog signal (I+,I-). Filter devices (FD) (20) filter the analog signal. The CD are designed so as to convert digital signals into an analog current signal. The FD have an impedance transfer function so that an outgoing signal from the FD corresponds to an analog filtered voltage signal (Vout). An independent claim is also included for a device for data transmission with a circuit structure according to the present invention.
