The invention discloses a current signal generating circuit and a current compensation device. The current signal generating circuit comprises a first analog-digital conversion circuit and a first digital-analog conversion circuit, wherein the first analog-digital conversion circuit comprises an input end and an output end, the input end receives a temperature signal which changes with the temperature, and the output end provides a first digital signal; and the first digital-analog conversion circuit comprises a first input end, a second input end and an output end, the first input end receives the first digital signal, the second input end receives a reference current signal, and a temperature current signal which has a setting relation with the temperature is provided at the output end of the first digital-analog conversion circuit based on the first digital signal and the reference current signal. The current signal generating circuit can generate a current signal which has a specific relation with the temperature, and the signal can be used for compensating the current signal, so that a current source which does not change with the temperature basically or has a setting relation with the temperature can be obtained.
