Design Techniques for CMOS Wireline NRZ Receivers Up To 56 Gb/s

Wireline receivers continue to target higher data rates, posing great challenges at circuit and architecture levels. Governed by tradeoffs among speed, power consumption, and channel loss (CL), receiver designs can benefit from new methods that push the performance envelope. This paper presents a number of techniques that allow non-return-to-zero data rates as high as 40 and 56 Gb/s in 45-nm and 28-nm CMOS technologies, respectively. The prototypes operate with a CL of 19-25 dB and a bit error rate of less than 10−12.
