Abstract :
A 4-lane, 2Gbps-per-lane, source synchronous, voltage-mode differential transmitter is presented here. Staggered switching of driver termination is used to obtain controlled, nearlinear rise/fall transitions on the pads. The timing for the staggering is generated by a calibrated digitally controlled delay line. An on-chip high bandwidth regulator serves as a low impedance 400mV source required for voltage mode transmission. The transmitter, designed and fabricated in 45nm CMOS technology, occupies a core area of 0.013mm2 per lane and consumes 4.3mW/Gbps.
