An electrical circuit is disclosed having a drive stage and a control stage suitable, for example, for operating an electric motor in an electrical power assisted steering system. The circuit comprises a drive stage (1) comprising at least a first conducting means and a control stage (2) comprising a second conducting means, the first conducting means comprising one or more conductive tracks or links (3) adapted to define an electrical circuit with an input terminal (7) extending from an end portion of at least one track for connection to a source of electrical current, the second conducting means (2) comprising a printed circuit board (4) defining tracks adapted to carry current to/from one or more control devices and supporting at least one track connected to a surface mounted de-coupling capacitor (9) supported by the printed circuit board (4), and in which a portion of the track of the first conducting means (1) is so constructed and arranged as to provide an electrical connection between the capacitor (9) and the terminal (7).
