Abstract :
A 2.3 to 5 GHz LC PLL is implemented in 65 nm standard CMOS for 0.6 to 10 Gb/s SerDes applications. The LC VCO is measured to have 67% coarse tuning range and worst-case hold range of 9.6%. The rms random jitter (RJrms) on the TX output with a clock pattern is measured to be 460 fs at 5 GHz and 548 fs at 3.125 GHz. The total power dissipated from the 1.8 V, 1.0 V supplies is 29 mW at 5 GHz.
