LEVEL-SHIFTER CIRCUIT USING LOW-VOLTAGE TRANSISTORS

A level-shifter circuit may include a pair of inputs which receive a first and a second low-voltage phase signal having a first voltage dynamic with a first maximum value. The level-shifter circuit may also include a pair of outputs which supply a first high-voltage phase signal and a second high-vo...

Beschreibung
Zusammenfassung:	A level-shifter circuit may include a pair of inputs which receive a first and a second low-voltage phase signal having a first voltage dynamic with a first maximum value. The level-shifter circuit may also include a pair of outputs which supply a first high-voltage phase signal and a second high-voltage phase signal, level-shifted with respect to the low-voltage signals and having a second voltage dynamic with a second maximum value, higher than the first maximum value. The level-shifter circuit may further include transfer transistors coupled between one of a first reference terminal and a second reference terminal, which are set at one of a first reference voltage and a second reference voltage, and the first output or second output. Protection elements may be coupled to a respective transfer transistor to protect from overvoltages between at least one of the corresponding conduction terminals and control terminals.
