Abstract
  • This work presents a new data encoding scheme: Integrated Pulse Width Modulation (iPWM) for equalizing lossy wireline channels with the aim of achieving energy efficient wireline communication. The proposed scheme is able to overcome the fundamental limitations imposed by Manchester and Pulse Width Modulation (PWM) encoding on high data rate wireline transceiver design. A highly digital scalable encoder architecture is leveraged to implement the proposed iPWM encoding. An energy efficient wireline transceiver implementation of the proposed scheme is demonstrated with measured results over a data-rate range of 10 to 18 Gb s. Fabricated in a 65nm CMOS process, the transceiver operates with supply voltages of 0.9V, 1V and 1.1V. It is capable of equalizing over 27dB of channel loss while operating at 16 Gb s with an efficiency of 4.37pJ bit. The design occupies anactive die area of 0.21 sq. mm.
