A current mirror circuit comprises a first transistor, a second transistor diode-connected in series to said first transistor, a third transistor whose base is connected to the base of said first transistor, a fourth transistor connected in series to the third transistor with the base connected to the base of said second transistor and a fifth transistor whose emitter is connected to the base of said first transistor, whose base is connected to the collector of said first transistor and whose collector is connected to the collector of said fourth transistor.
