Abstract
An electronic circuit including: a first branch, placed between two terminals of application of a D.C. voltage, including a series connection of a first constant current source, of a first diode-connected N-channel MOS transistor, of a first diode-connected P-channel MOS transistor, and of a second constant current source; a second branch, parallel to the first branch, comprising a series connection of a second N-channel MOS transistor connected as a current mirror on the first N-channel MOS transistor and of a second P-channel MOS transistor connected as a current mirror on the first P-channel transistor; and an input terminal connected between the first N-channel and P-channel transistors and an output terminal connected between the second N-channel and P-channel transistors.
