Zusammenfassung:	A temperature compensated oscillation circuit is provided. The temperature compensated oscillation circuit generates a first delay voltage and a second delay voltage according to the first resistance value. A first order term of a temperature change function of the first resistance value is eliminated. The temperature compensated oscillation circuit generates a reference voltage according to a first reference resistance value and a second reference resistance value. A first order term of a temperature change function of the first reference resistance value is set to equal to a first order term of a temperature change function of the second reference resistance value. The second reference resistance value is adjusted such that variation of the reference voltage matches a second order term of the temperature change function of the first resistance value, thereby providing a clock that does not vary due to a variation in temperature.
