Abstract: An amplifier arrangement includes an output amplifier stage (OA) comprising a stage input (SIN), a stage output (SOUT) which is coupled to a signal output (OUT) of the amplifier arrangement, and a capacitive element (CE) which couples the stage output (SOUT) to the stage input (SIN). A driver stage (DR) comprises a driver input (DIN) and a driver output (DOUT) which is coupled to the stage input (SIN). The driver stage (DR) is configured to generate a voltage potential at a driver output (DOUT) depending on an input current at the driver input (DIN) and to provide a charging current to the capacitive element (CE) being higher than the input current.

Abstract: A voltage regulator for electrically programmable, non-volatile memory devices has an output terminal connected to a power supply line for programming the state of at least one memory element through at least one selection circuit. At least first and second resistive elements are connected between first and second terminals of a voltage supply. At least a first circuit is matched to the at least one selection circuit, and the first circuit is coupled serially with the resistive elements between the two terminals of the voltage supply. At least one control current generator is connected between one of the first and second voltage supply terminals and a node linking to one of the resistive elements, and the current of the controlled current generator is controlled to be a function of current through the at least one selection circuit. An operational amplifier has an inverting input and a non-inverting input, and the non-inverting input is connected to a node linking to at least one of the resistive elements.
