Abstract:
A current mirror circuit includes: a first transistor and a second transistor connected in series, a third transistor and a fourth transistor connected in series; and further includes: a reference voltage source, a fifth transistor, and a control module connected between the reference voltage source and the fifth transistor. A current mirror is formed by the third transistor and the fourth transistor together with the first transistor and the second transistor, to produce a mirror current at a drain of the third transistor according to a current source coupled to a drain of the first transistor; the control module is configured to control the fifth transistor to operate in the linear region.
