Abstract
A current generation circuit includes a temperature sensing circuit, a resistor element having a resistance, and a current mirror circuit. The temperature sensing circuit is configured to generate a reference voltage having corresponding magnitude according to a temperature of the current generation circuit. The resistor element is coupled with the temperature sensing circuit, and is configured to determine magnitude of a reference current according to the reference voltage and the resistance. The current mirror circuit is coupled with the temperature sensing circuit, and is configured to generate an output current according to the reference current. The temperature sensing circuit and the resistor element both have positive temperature coefficients or negative temperature coefficients.
