Abstract:
A voltage level translator circuit has a digital logic circuit having a digital logic signal, at least one high-voltage capacitor having a first and second connection, wherein one of the first and second connections is electrically coupled to the digital logic signal, and a cross-coupled inverter pair having, the output of at least one inverter of the pair electrically coupled to the other connection of the at least one high-voltage capacitor. A high-voltage driving circuit has two low-voltage input signals, two high-voltage output signals, a first signal being a high-side drive signal and a second signal being a low-side drive signal, two level translators, a first level translator corresponding to the high-side drive signal, and a second level translator corresponding to the low-side drive signal, the level translators including a digital logic circuit having a digital logic signal, at least one high-voltage capacitor having a first and second connection, wherein one of the first and second connections is electrically coupled to the digital logic signal, and a cross-coupled inverter pair having, the output of at least one inverter of the pair electrically coupled to the other connection of the at least one high-voltage capacitor.
