Abstract
A level shifter circuit configured to shift an input signal switching within a first voltage range to generate a first output signal correspondingly switching within a second voltage range higher than the first voltage range. The level shifter circuit including a latching core having latching input and output terminals and a supply line configured to be supplied by a supply voltage, and a reference line configured to be coupled to a reference voltage. Capacitive coupling elements are coupled to the latching input and output terminals of the latching core. A driving stage is configured to bias the capacitive coupling elements with biasing signals generated based on the input signal. A decoupling stage is configured to be driven by the driving stage through the capacitive coupling elements to decouple the supply line from the supply voltage and the reference line from the reference voltage during switching of the input signal.
