A 0.18 μm CMOS 10-Gb/S multichannel transmitter with duty-cycle correction

This paper describes a multichannel transceiver targeting IEEE 802.3ae (10-Gb/s) Ethernet standard using 0.18 μm CMOS process. The transmitter sets features: 1) Multiphase clock to multiplex the data; 2) Duty-cycle correction (DCC) circuit to adjust the clock pulse width; 3) Current-mode linedriver to drive transmitter medium. Through simulation, the total jitter (peak-to-peak) is 45 ps, power dissipation is 140 mW, and total latency is 24 ns. Differential output voltage swing of transmitter is 1.6 V.
