Voltage controlled crystal oscillator

摘要

The novel approach reported in this paper optimizes the dynamic noise and drive sensitivity factor for achieving low phase noise voltage controlled crystal oscillator circuit (VCXO). An example of 100 MHz mode feedbacks and differential coupled VCXOs are demonstrated for the validation of this new approach, which offers 10–15 dB phase noise reduction, therefore, spectral pure, power-efficient and cost-effective solutions.
