A single-input multi-output control system particularly useful to equally distributing the noise effects and/or the parametric variations among the multiple outputs, comprising two or more control sub-systems, each of said two or more control sub-systems having a corresponding error node (Ne.sub.i) and an output (Y.sub.i) coincident with one of said multiple outputs, and an auxiliary node (Nc) adapted to connect said error nodes (Ne.sub.i) with one another.
