- *Abstract
-
A dual-band LC oscillator was developed at Cornell that demonstrates the first ideally-coupled structure and achieves band switching without impairing phase noise performance. This invention addresses a major challenge in wireless design by covering a wide frequency spectrum while still meeting stringent phase noise requirements. The dual-band oscillator achieves the same phase-noise figure-of-merit (FoM), 3 dBc/Hz lower phase noise, and twice the tuning range as a single-band LC oscillator that uses the same inductor and active core, based on analysis and verified by prototype measurements in a 0.13 µm CMOS process.
Potential Commercial Applications:
- Low-phase-noise applications, e.g. multi-mode communication terminals, clock-data-recovery (CDR) circuits, software-defined radios, etc.
Advantages:
- Generates multi-frequency resonant signals at low phase-noise
- Maintains quality factor
- CMOS compatible
