Abstract
A level-shift circuit, comprising: an input, for receiving a first voltage; an output, for outputting a second voltage; a resistor array comprising one or more resistors connected in series to the input; a current sink for providing a current that is independent of the first voltage; a switch arrangement comprising a plurality of switch connections for establishing a selected one from a plurality of force paths between the current sink and the input, the selected force path comprising a selected number of the one or more resistors of said resistor array; and at least one connection between the output and the resistor array that provides a sense path between the resistor array and the output that does not comprise any of the switch connections used to establish each of the plurality of force paths.
