Patent ID: 8495273

Claim:
An apparatus including a switch having a first channel and a second channel, comprising: a first terminal that receives a negative portion of a differential auxiliary signal; a second terminal that receives a positive portion of the differential auxiliary signal; a third terminal; a fourth terminal; a first switch that is coupled between the first terminal and the third terminal; a second switch that is coupled between the second terminal and the fourth terminal; a first precharge circuit that is coupled to the first terminal; a second precharge circuit that is coupled to the second terminal; and a controller that is coupled to the first switch, the second switch, the first precharge circuit, and the second precharge circuit, wherein the controller activates the first and second precharge circuits while the first and second switches are deactivated, and wherein the controller activates the first and second switches while the first and second precharge circuits are deactivated, wherein the first and second precharge circuits further comprise first and second switched voltage dividers, respectively, wherein the first switched voltage divider further comprises: a third switch that receives a first voltage and that is coupled to the controller so as to be controlled by the controller; a fourth switch that receives a second voltage and that is coupled to the controller so as to be controlled by the controller; a first resistor that is coupled between the third switch and the first terminal; and a second resistor that is coupled between the fourth switch and the first terminal.
