A representative level-shifter comprises a dynamically biased current source circuit that receives a first voltage, a first and a second unidirectional current-conducting devices, a first and a second pull-down devices, and a pull-up device. The first and second unidirectional current-conducting devices are coupled to the dynamically biased current source circuit. A voltage output of the level-shifter is located at a first node that is located between the current-constant circuit and the second unidirectional current-conducting device. The first and second pull-down devices are coupled to the first and second unidirectional current-conducting devices, respectively. The pull-up device receives a second voltage and is coupled to the dynamically biased current source circuit and the first unidirectional current-conducting device. The pull-up device is configured to dynamically bias the dynamically biased current source circuit such that a voltage drop of the second unidirectional current-conducting device is output at the voltage output responsive to the pull-up device outputting the second voltage to the dynamically biased current source circuit, the first pull-down device being non-conducting and the second pull-down device being conducting.
