Abstract
The device generates a reference voltage, in particular designed for a system of the switched-capacitor type, based on a setpoint voltage. It includes a regulation loop having a first input to receive the setpoint voltage, and an output stage arranged as a voltage follower and looped to a second input of the loop. An additional stage is configured to deliver the reference voltage to the switched-capacitor system, this additional stage, coupled to the output stage, also being arranged as a voltage follower and paired with the output stage.
