摘要
To provide a relaxation type oscillator in which temperature deviation of oscillation frequency is extremely small.SOLUTION: A first resistor having a positive primary temperature coefficient and a first current Igenerated in a reference voltage source are supplied to a first variable capacitor C, and a second resistor having a negative primary temperature coefficient and a second current Igenerated in the reference voltage source are supplied to a second variable capacitor C. The product of ratios of the primary temperature coefficient of the second resistor to that of the first resistor has the same absolute value and the opposite sign of the value of ratio of the capacitance of the first variable capacitor to that of the second variable capacitor.SELECTED DRAWING: Figure 1
