28 nm IEEE 802.11ax transceiver and why it is so difficult to make!
There is continuous demand for higher wireless data rates. As a consequence, the Wi-Fi Alliance is continuously generating new standards to keep up with this demand. Most recent additions are the IEEE 802.11ac and the emerging 11ax standards. The penalty for packing ever-increasing data rates into the same channel bandwidths is increased system complexity and tighter specifications. This makes the design of transceivers meeting these standards much more challenging than for regular Wi-Fi devices. This talk sheds some light on the sources of the tougher requirements and gives an outline of a recent 28 nm transceiver design that meets the 11ax specifications.
