Abstract :
A 20Gb/s transmitter is implemented in 0.13μm CMOS technology. Eight 2.5Gb/s data streams are 4:1 multiplexed, sampled, and retimed into two 10Gb/s data streams. A final 20Gb/s 2:1 output multiplexer, clocked by complementary phases of an LC-VCO (voltage controlled oscillator) in a phase-locked loop, creates 20Gb/s data. The VCO is integrated with the output multiplexer, resonating the load and eliminating the need for clock buffers. Power, active die area, and jitter (RMS/pk-pk) are 165mW, 650μm × 350μm, and 2.37ps/15ps, respectively.
