Abstract:
1. An oscillator comprising: a first resistor (R 1 ), a second resistor (R 2 ), and a capacitor, wherein an oscillation frequency of the oscillator is dependent upon a difference between a first resistance value of the first resistor (R 1 ) and a second resistance value of the second resistor (R 2 ), the first resistance value being larger than the second resistance value, the first resistor (R 1 ) exhibits a first rate of change with temperature, and the second resistor (R 2 ) exhibits a second rate of change with temperature that is larger than the first rate of change, thereby allowing temperature-induced changes to the first resistance value to be offset by changes to the second resistance value, and thereby reducing variations in the oscillation frequency with temperature.
