Abstract
1,020,080. Oscillator circuits. CSF. COMPAGNIE GENERALE DE TELEGRAPHIE SANS FIL. Dec. 30, 1963 [Jan. 4, 1963], No. 51233/63. Heading H3F. Drift in an electronic circuit due to temperature variations is compensated by the change in capacity of a reversely biased semi-conductor diode to which is applied a voltage varying as a function of temperature. The invention is described as applied to a quartz crystal oscillator comprising an amplifier A (Fig. 2, not shown), giving zero phase-shift and with feed-back between its input and output terminals over the quartz crystal-Q. The semi-conductor diode C is connected in series with the quartz crystal Q and has applied to it the variable back bias V from source G. The source G may comprise a potentiometer network formed of resistors R1-R3 (Fig. 3, not shown), in which resistors R1, R2 are connected in series across a constant potential source and resistor R1 is shunted by a thermistor r; the control voltage is taken across resistor R2 via series resistor R3. In a modification (Fig. 4, not shown) giving compensation in the opposite sense, the thermistor is connected across the resistor from which the control voltage is taken. In a further modification a potential varying in one sense is derived from a potentiometer comprising resistors R1-R3 and thermistor r, Fig. 6, and one varying in opposite sense from a potentiometer comprising resistors R4-R6 and thermistor r<SP>1</SP>. The two voltages are combined via diodes D1, D2 which prevent each source from having a modifying effect on the other.
