| Popis: | As data rates continue to increase, the reach of electrical interconnects is becoming shorter due to loss and distortion of the signal. Optical interconnects based on vertical-cavity surface-emitting lasers (VCSELs) provide a cost-effective solution to transfer data over tens of meters in data centers. However, integrating optical transceivers within a server platform requires improved bandwidth density and energy efficiency. High data-rate, compact area, and energy-efficient transmitter (TX) circuits that mitigate VCSEL nonlinearity and bandwidth limitations are key enablers of this integration. This paper presents an optical TX implemented in 28nm bulk CMOS which drives an 850nm VCSEL up to 56Gb/s. |
