Abstract
A selector switch may be controlled by a single-ended control signal for steering a current through a load or through an auxiliary line. The selector switch may include a first terminal to be coupled to the load, and a second terminal to be connected to the auxiliary line, and two analog switches coupled to respective ones of the first and second terminals and configured to implement a single pole double throw switch so that a conduction or non-conduction state is determined by the single-ended control signal for steering the current through the load or the auxiliary line. The selector switch may also include a circuit defining a positive feedback loop controlling the two analog switches.

A selector switch to be controlled by a single-ended control signal for steering a current through a load or through an auxiliary line, the selector switch comprising:
- a first terminal to be coupled to the load, and a second terminal to be coupled to the auxiliary line;
- respective analog switches coupled to said first and second terminals and configured to implement a single pole double throw switch so that a conduction state or a non-conduction state is determined by the single-ended control signal for steering the current through the load or the auxiliary line;
- and
- a circuit defining a positive feedback loop controlling said analog switches.
A selector switch to be controlled by a control signal for steering a current through a load or through an auxiliary line, the selector switch comprising:
- a first terminal to be coupled to the load, and a second terminal to be coupled to the auxiliary line;
- respective analog switches coupled to said first and second terminals and configured so that a conduction state or a non-conduction state is determined by the control signal for steering the current through the load or the auxiliary line;
- and
- a positive feedback loop controlling said analog switches.
An electronic device comprising:
- a plurality of selector switches coupled together, each selector switch to be controlled by a control signal for steering a current through a load or through an auxiliary line, each selector switch comprising
- a first terminal to be coupled to the load, and a second terminal to be coupled to the auxiliary line,
- respective analog switches coupled to said first and second terminals and configured so that a conduction state or a non-conduction state is determined by the control signal for steering the current through the load or the auxiliary line, and
- a positive feedback loop controlling said analog switches.
A method for making a selector switch to be controlled by a control signal for steering a current through a load or through an auxiliary line, the method comprising:
- providing a first terminal to be coupled to the load, and a second terminal to be coupled to the auxiliary line;
- coupling respective analog switches the first and second terminals and configured so that a conduction state or a non-conduction state is determined by the control signal for steering the current through the load or the auxiliary line;
- and
- coupling a positive feedback loop to control the analog switches.
