Abstract
A replica circuit includes: a first conductivity type first transistor; a first current path including a first conductivity type second transistor and a second conductivity type third transistor; a second current path including a first conductivity type fourth transistor configured so that current equivalent to a current flowing through the first transistor flows through the fourth transistor, and a second conductivity type fifth transistor configured so that current equivalent to a current flowing through the third transistor flows through the fifth transistor, the fourth transistor and the fifth transistor being connected in series; a second conductivity type sixth transistor configured so a current equivalent to a current flowing through the third transistor flows through the sixth transistor; a first control configured to supply a reference voltage to the drain of the first transistor; and a second control configured to supply the reference voltage to the drain of the fourth transistor.
