Abstract :
This paper presents the improvements of the temperature coefficient of the VHF oscillator circuit for OCXO. The solution for this discrepancy, not only to regulate the temperature precisely, but also the temperature coefficients of oscillator loop itself should be considered and reduced for better frequency-temperature performance to get higher frequency stability for the OCXO.
