Correcting circuit heating on chip

The invention discloses a chip parameter temperature coefficient correcting circuit applied to chip heating. The chip parameter temperature coefficient correcting circuit comprises an adjustable current source generation device, at least two heating weak-current sources, a heating source and a gating switch, wherein the adjustable current source generation device is used for generating adjustable current; the at least two heating weak current sources are used for providing heating weak current according to the adjustable current; the heating source is used for heating a chip according to heat generated by the current so as to adjust the environmental temperature of the chip; and the gating switch is used for controlling the heating weak current source or a ground wire to be connected to the heating source in a gate way. The chip parameter temperature coefficient correcting circuit has the characteristics that a parameter to be adjusted is changed by utilizing the heating source on the chip to generate the env
