摘要： The present disclosure describes a low-power, low-phase-noise (LPLPN) oscillator. The LPLPN oscillator includes a resonator load, an amplifier stage, and a loop gain control circuit. The resonator load is structured to resonate at a primary resonant frequency. The amplifier stage is coupled with the resonator load to develop a loop gain that peaks at the primary resonant frequency. The loop gain control circuit is coupled with the amplifier stage, and it is structured to regulate the loop gain for facilitating the amplifier stage to generate an oscillation signal at the primary resonant frequency and suppress a noise signal at a parasitic parallel resonant frequency (PPRF).

摘要： A clock oscillator includes with a pullable BAW oscillator to generate an output signal with a target frequency. The BAW oscillator is based on a BAW resonator and voltage-controlled variable load capacitance, responsive to a capacitance control signal to provide a selectable load capacitance. An oscillator driver (such as a differential negative gm transconductance amplifier), is coupled to the BAW oscillator to provide an oscillation drive signal. The BAW oscillator is responsive to the oscillation drive signal to generate the output signal with a frequency based on the selectable load capacitance. The oscillator driver can include a bandpass filter network with a resonance frequency substantially at the target frequency.
