Abstract: An output stage comprising a current mode line driver, a voltage mode line driver, and a center-tapped transformer for coupling data provided by the line drivers to a transmission line is provided herein. The output stage is configured to operate in a backwards compatible Ethernet communication device. For example, the Ethernet communication device is configured to support 10G Ethernet and legacy Ethernet modes of 10BASE-T, 100BASE-T, and 1000BASE-T. The current mode line driver can be utilized while operating in the 10G Ethernet mode to provide high linearity. The voltage mode line driver can be utilized while operating in legacy mode to conserve power. In order to accommodate the use of two different line drivers, a switch and/or a voltage regulator is used to couple/decouple a dc voltage to a center-tap of the transformer based on which of the two different line drivers is currently active.

TL;DR: In this paper, a method and system for detecting packets of different formats in a wireless receiver is disclosed, which includes initializing the receiver to be in a legacy mode; and receiving at least one data symbol by the receiver.
Abstract: A method and system for detecting packets of different formats in a wireless receiver is disclosed. The method and system include initializing the receiver to be in a legacy mode; and receiving at least one data symbol by the receiver. The method and system include detecting if there is a high throughput (HT) signal field within a data packet and determining the format of the data packet based upon the detection of a HT signal field.
