This brief presents a fully integrated integer-N frequency synthesizer with a frequency-tuning range from 2.4 to 2.9 GHz and root-mean-square (rms) jitter below 2.5 ps over 350 MHz. The employed architecture using an inductance-capacitance (L-C) oscillator with two control inputs combines a wide tuning range with a low noise sensitivity. Potential applications include clock generation in microprocessors and clock recovery in fiberoptic receivers.
