Abstract
An integrated ramp, sweep fractional frequency synthesizer system on an integrated circuit chip includes an integrated circuit chip having a fractional frequency synthesizer with a fractional divider responsive to a VCO and a ΔΣ modulator for modifying the divisor of the fractional divider; and a ramp generator on the same integrated circuit chip; the ramp generator being responsive to a trigger signal to generate a ramp for sweeping the frequency of said fractional frequency synthesizer.
