Abstract
The present disclosure concerns a device for supplying an adjustable current configured to supply discrete values of the current belonging to different current ranges, with a pitch between two successive discrete values determined by that of said ranges to which each of the two successive discrete values belongs.
Claims20
A device comprising:
- a first source of a first current at a first node, the first source configured to supply a different value of the first current for each of different current ranges;
- and
- a second current source configured to supply, to a second node, at least from the first current and a digital control signal, discrete values of an adjustable current belonging to different current ranges, with a pitch between two successive discrete values determined by that of the current ranges to which each of the two successive discrete values belongs.
A method of supplying an adjustable current, the method comprising:
- supplying discrete values of the adjustable current belonging to different current ranges, with a pitch between two successive discrete values determined by that of the current ranges to which each of the two successive discrete values belongs.
An electronic circuit comprising:
- a MOS power transistor;
- a device configured to supply discrete values of an adjustable current belonging to different current ranges, with a pitch between two successive discrete values determined by that of the current ranges to which each of the two successive discrete values belongs;
- and
- a circuit for driving the MOS power transistor configured to draw or to supply a control current from or to a gate of the MOS power transistor according to a binary control signal,
- wherein the control current is determined by the adjustable current.
