ABSTRACT:
A current generator stage for integrated analog circuits includes a current source connected between a supply voltage and a ground terminal. A current mirror is operationally connected to the current source to generate an output current. A bias circuit is operationally connected to the current source to perform switching of the current source from a first operating mode to a second operating mode. The bias circuit includes an energy storage circuit which, in a first circuit configuration, supplies to the current source a first predetermined voltage when the current source is in the first operating mode. The energy storage circuit in a second circuit configuration is a combination of first and second reactances to supply to the current source a second predetermined voltage when the current source is in the second operating mode.
