Abstract:
A controlled current source having a control input intended to receive a control signal, and an output intended to supply a current whose value depends on the value of the control signal, comprising:a plurality of parallel-arranged power transistors each having a reference terminal, a transfer terminal and a bias terminal, the transfer terminals of the power transistors being jointly connected to the output of the current source, anda control module having an input intended to receive the control signal, and an output intended to supply a signal enabling the power transistors to be turned on, wherein the reference terminals of the power transistors are jointly connected to the output of the control module, said output supplying a current whose value depends on the value of the control signal, the bias terminals of the power transistors being permanently subjected in the operative state of the current source to a voltage of a predetermined value enabling said power transistors to be rendered potentially conducting.
