Abstract :
The paper presents a temperature compensated 100MHz reference oscillator based on a capacitive silicon bulk acoustic wave (BAW) resonator interfaced with a CMOS amplifier. The resonator is optimized for high quality factor (92000) and low impedance. The CMOS IC comprises of a transimpedance amplifier to sustain oscillations and an oven control mechanism for temperature control. A phase noise floor of -136dBc/Hz was measured for the oscillator and the temperature drift of frequency was measured to be 56ppm over 100degC
