Abstract :
A fully differential 40-Gb/s cable driver with adjustable pre-emphasis is presented. Based on a distributed limiting architecture, the circuit can supply up to 3.6 V peak-to-peak per side in a 75 Omega load with variable pre-emphasis ranging from 0 to 400%. S-parameter measurements show 42 dB differential small-signal gain, a bandwidth of 22 GHz, gain peaking control up to 25 dB at 20 GHz and input and output reflection coefficients better than -lOdB up to 40 GHz. Additional features of the driver include output amplitude control (from 1 Vpp to 3.6 Vpp per side), pulse-width control (35% to 65%) and an adjustable input DC level (1.1 V to 1.8 V) allowing the circuit to interface with a SiGe BiCMOS or MOS-CMLSERDES.
