Abstract
A rectifier circuit is described, which comprises an arrangement of a first, a second and a third transistor, emitters of said transistors being coupled together at a first junction point and to a terminal of a first constant current source and in which arrangement collectors of the first and the second transistor are coupled together at a second junction point, a current mirror arrangement having a predetermined mirror ratio, an input of said current mirror being coupled to the second junction point and an output of said current mirror being coupled to a collector of the third transistor at a third junction point, wherein an input voltage, by which the collector-emitter currents of the first and/or the second transistor are controllable, can be supplied to the rectifier circuit bia bases of the first and/or the second transistor, while an output voltage can be taken from the base of the third transistor of the rectifier circuit and the output voltage at least substantially corresponds to the rectified input voltage, and the first, the second and the third transistor have predetermined emitter regions. To provide a rectifier circuit of a simple structure, ensuring an at least subst…
