A novel low power, low phase noise CMOS oscillator based on thin film bulk acoustic resonator (FBAR) is submitted in this paper, which aims at application in wireless sensor networks. This oscillator is designed as current-reuse configuration to reduce power dissipation. The simulation results show that the oscillator operating at 1.878 GHz consumes 1.8 mW with a low supply voltage of 900 mV. That is only a half of power consumption of the conventional topologies. Moreover, its phase noises are -107 dBc/Hz and -135 dBc/Hz at 10 kHz and 100 kHz offsets respectively, and its FOM is -238 dBc/Hz.
