A 12-Gb/s transceiver in 32-nm bulk CMOS

A 12-Gb/s transceiver in 32-nm bulk CMOS in described. Features include an 8.8–12.4-GHz LC-PLL with 0.4-ps jitter; a full-swing DLL and phase interpolator with LSB=2.6 ps and DNL≪1.2 ps; a 4.2-mW receiver front end with de-muxing comparator and precharge removal latch; and an all-digital duty cycle correction (DCC) loop. The transceiver receives and transmits PRBS23 data at 12 Gb/s with BER≪10⁻¹² over a 6-in FR4 channel with 10 dB of loss, while consuming 37.8 mW (3.15 pJ/bit) from a 1-V supply, not including clock generation. A chip-to-chip link transmits and receives PRBS15 data at 11.6 Gb/s with BER≪10⁻¹² over a 12-in. FR4 channel.
