Abstract
An active rectifier used in a power supply circuit comprises a diode (4) connected between in input terminal (9) and an output terminal (8). A transistor (2) is formed in a substrate (50) and has a control electrode (5) and two conductive electrodes (6,7) which are respectively connected to the input terminal (9) and the output terminal (8). A comparator (3) is supplied by the power supply circuit and has two inputs (+, -) connected to the input (9) and the output (8) terminals respectively, and an output connected to the transistor control electrode (5).
