Abstract :
This paper describes the design and measured performance of a low-noise varactor tuned oscillator based on a film bulk acoustic resonator (FBAR) at 2 GHz. Using varactor tuning, this oscillator demonstrated a 2.5 MHz frequency tuning range at 1985 MHz with a phase noise of -112 dBc/Hz at 10 kHz from the carrier. This represents the first example of a low noise Si-bipolar FBAR tunable oscillator.
