Abstract

This paper presents a new method of substantially improving frequency pullability and linearity using reactance in series with an AT fundamental crystal operated with a series load capacitance in the range of 3 to 50 pF andfrequencies in the range of 3.5 to 21 MHz. The research describes high quartz pullability and linearity by varying the load capacitance. The paper also gives impedance circuits for crystal unit (3.5 MHz) together with load capacitance and compensation reactance. The experimental results show that thenew approach using compensation method of quartz crystal connected in series reactance increases the frequency pulling range by *25 to *100 depending on the type of oscillator and compensation factor k in the temperature range of 10 to 40 °C.
