An active current regulator circuit. In one embodiment, the active current regulator circuit includes a first input node for receiving a first reference electrical signal, a second input node for receiving a second reference electrical signal, a ground node, and an output node for outputting an output electrical signal with respect to the ground node. The active current regulator circuit further includes a PI controller having a first input node, a second input node, and an output node, and a linear regulator having a first input node electrically coupled to the output of the PI controller for receiving a voltage signal V<SUB>0 </SUB>generated the PI controller, a first output node and a second output node. In operation the voltage signal V<SUB>0 </SUB>is responsive to at least one input voltage signal applied to the first input of the second input of the amplifier, and drives the linear regulator to have a controlled electrical signal at its first output node accordingly.
