Abstract
An active precision termination of the type incorporated in a voltage regulator for feeding the lines of an external bus is presented. Each termination includes a matching impedance connected in series to a switch formed by a MOS transistor, including a cell formed by a plurality of circuit branches provided in parallel and coupled to a unique output terminal. Each branch includes an input coupled to the series of the impedance and of the switch and receiving a control voltage signal. The body terminal of each MOS transistor receives a corresponding control signal via an inverter, whereas the control terminal of each MOS transistor receives a corresponding control voltage signal.
