The PLL's loop dynamics are analyzed in depth and theoretical relationships between all loop parameters are clearly described. All the parameters are derived and verified by Verilog-A model, which ensures the accuracy and efficiency of the circuit design and simulation. A 4-stage ring oscillator is employed to generate 1-GHz oscillation frequency and is divided into low frequency clocks by a feedback divider. The architecture is a third-order, type-2 charge pump PLL. The simulated settling time is less than 4μs. The RMS value of period jitter of the PLL's output is 2.1 ps. The PLL core occupies an area of 0.12 mm2, one fourth of which is occupied by the MiM loop capacitors. The total current consumption of the chip is 16.5 mA. The chip has been sent for fabrication in 0.13 m complementary metal oxide semiconductor (CMOS) technology.展开更多

Simple and effective pre-emphasis and equalizer circuits are used in the transmitter and receiver, respectively.

With an on-chip fully integrated phase locked loop, the transceiver works at data rates of 100 Mb/s, 400 Mb/s, and 800 Mb/s, supporting three different operating modes of S100b, S400b, and S800b for IEEE 1394b. The chip has been fabricated using 0.13 μm technology. The die area of transceiver is 2.9×1.6 mm2 including bonding pads and the total power dissipation is 284 mW with 1.2 V core supply and 3.3 V input/output supply voltages.展开更多
