A current generating circuit may include a first current source configured to generate a first current having positive temperature characteristics; a second current source configured to generate a second current; a compensation transistor configured as an NPN bipolar transistor, and arranged such that the second current flows through from its collector and its emitter; and a first current mirror circuit configured to multiply a base current of the compensation transistor by a first coefficient so as to generate a third current. The current generating circuit may be configured to output a fourth current that is proportional to the difference between the first current and the third current.
