A full-rate ADSL central-office line driver consumes 610mW through active termination and a zero-overhead class G technique. The supply switching scheme features very low overhead voltage, logic control, and controlled supply-rail ramp rate, and requires analog signal-peak prediction to be performed on the digital data stream.
