Abstract
Described is a frequency synthesizer having a wide output frequency range and small frequency tuning steps. In-band spurious components are maintained at low levels and phase noise is significantly reduced. The frequency synthesizer can be fabricated as an integrated circuit device having a small area and low power dissipation. The frequency synthesizer can be used in wideband frequency systems to reduce cost and size by replacing multiple frequency synthesizers each devoted to a portion of the overall system frequency range.
