We propose a new dynamic D-latch for low-power high-speed SerDes in chip-to-chip optical interconnect. The overall SerDes circuit uses 3.6 times less number of transistors, with smaller SerDes occupying 50% less area, compared to the previous works. The SerDes operates up to 10 Gbps data rate, and the power consumption is 49.3 mW at 1.8 V, which is 30 % less power.
