Frequency Stability Analysis of a Grounded-Base Voltage-Controlled Crystal Oscillator

The frequency stability is analyzed for a voltage-controlled grounded-base crystal oscillator by matrix algebra. The validity of the resulting equation was verified by measurements on an oscillator with a 110-MHz fifth-overtone quartz crystal. Sensitivity coefficients for the oscillator are computed with the aid of a time share computer program and its sweep range is drawn by a plotting routine.
