Abstract
A line driver for generating 10 BT signals is disclosed. Digital symbols to be transmitted via a 10 BT Ethernet line are converted by a digital-to-analog converter into a corresponding analog voltage signal, which is fed into an active output impedance line driver. The digital-to-analog converter also receives a reference voltage reflecting variations of the supply voltage and adjusts its output signal accordingly to provide a deliberately variable analog voltage signal to the line driver.
