Current drive circuit
Abstract:
A current drive circuit according to the present invention includes: a first current source and a second current source (I101, I102); a first current mirror (CM103) for generating a first mirror current of a current (I2) generated by the second current source (I102); a second current mirror (CM106) for generating a second mirror current of the current (I2) generated by the second current source (I102); and a third current mirror (CM101) for generating a mirror current (IOUT1) of a current which is generated by the first current source (I101) and which is corrected according to a difference between the first mirror current and the second mirror current, to supply the current to a load (LD101).
