Abstract
A current generator for the production of a reference current includes a first P type transistor, a source of which is connected to a first pole of a resistor and a gate of which is connected to a second pole of the resistor. The reference current flows in the resistor with a value that is a function of a threshold voltage of the first transistor. The current generator further includes a second N type transistor whose drain, gate and source are connected respectively to the second pole of the resistor, the first pole of the resistor and the drain of the first resistor. The second transistor is configured to operate in saturation mode.
