Abstract
A controllable bus terminator, for providing a switchable termination on a bus having a plurality of conductors, wherein the controllable bus terminator includes a voltage regulator, a plurality of resistive networks each of the resistive networks having a first terminal and a second terminal wherein the second terminal of each of the resistive networks provides an output terminal of the bus terminator. The bus terminator further includes a plurality of electrically controllable switches, each of the switches having a first port coupled to the voltage regulator and a second port coupled to the first terminal of a corresponding one of the resistive networks wherein each of the switches couple the corresponding resistive network to the voltage regulator when the corresponding switch is in a first state and wherein each of the switches disconnect the corresponding resistive network from the voltage regulator when the corresponding switch is in a second state.
