LC-based PLLs have historically been difficult to design due to poor modeling of integrated inductance, substrate losses, and package parasitics. In addition, classical LC PLLs have a very narrow frequency tuning range making it possible that the VCO will not be capable of oscillation at the desired frequency. However, Silicon Creations has overcome these problems in two ways:

  • First, a high quality coarse tuning element is used which gives a single VCO a wide tuning range to overcome PVT variations and model inaccuracy.
  • Additionally, a multiple VCO core design has been developed and can be used to cover up to a 2:1 frequency range.

Silicon Creations has LC PLL designs in technologies from 28nm to 180nm CMOS and with frequencies from 1.4GHz to 8.25GHz. Applications range from optical communications to RF synthesis.
