摘要：

A connecting arrangement includes a number of NMOS transistors that can be activated or deactivated by means of a control voltage, serving as a control signal, connected to the gate terminals of transistors, to be able to form a circuit connected between two conductors, the circuit presenting resistive properties. The circuit is equipped with a signal receiver and it is regulated by an analog control voltage. The control voltage is connectable to one or several of a number of available control connections. Each control connection is connected to the gate terminals of a group of transistors where the drain and source terminals are connected to the conductors. The control voltage is selected so that the operating point of the transistors will be within, or at least close to, the region where the transistor presents resistive properties.
