Provided are a reference current generating method and a current reference circuit. The reference current generating method includes generating a first current using a NMOS transistor and a second current using a PMOS transistor, calculating a current difference between the first and second currents, generating a third current which has a similar current/temperature slope as the second current by multiplying the current difference by a proportional constant, and generating a reference current by subtracting the third current from the second current.
