Abstract

A voltage level shifter includes an input stage with series-connected first and second N-type field effect transistors (NFETs) and an output stage with an inverter connected to an intermediate node between the first and second NFETs. Gates of the first and second NFETs are connected to an output node of the inverter and an input node, respectively. An input voltage signal on the input node toggles between a first voltage and ground. An intermediate voltage signal on the intermediate node toggles between a second voltage (lower than the first voltage) and ground. An output voltage signal on the output node toggles between the second voltage and ground. A capacitor in the input stage is connected between the input and intermediate nodes so that, when the input voltage switches to ground, the intermediate voltage signal is pulled to ground to facilitate switching of the output voltage signal to the second voltage.
