Abstract
Proposes a new frequency synthesizer architecture which uses a combination of known techniques. The architecture is evaluated by simulation and shown to reduce spurious content of existing fractional-N synthesizers. It also allows arbitrarily small channel spacing with existing fractional-N synthesizers.
