Abstract
A local oscillator (LO) generator architecture using a wide tuning range oscillator is disclosed. In one embodiment, a wide tuning oscillator based LO generator system includes a wide tuning range oscillator for generating a signal with a first initial frequency or a second initial frequency in response to a control voltage, a first frequency controlling circuit for converting the first initial frequency of the signal into a final frequency, and a second frequency controlling circuit for converting the second initial frequency of the signal into the final frequency.
