Abstract
An apparatus is disclosed for translating a lower voltage signal, utilized in a low voltage integrated circuit, to a higher voltage signal suitable for use in a high voltage circuit. The apparatus includes a low voltage transistor assembly capable of operating in response to the lower voltage signal; a voltage regulator which is configured to limit an applied voltage across the low voltage transistor assembly; and a high voltage converter which is responsive to the operation of the low voltage transistor assembly to generate the higher voltage signal. The voltage regulator includes a reference voltage generator and a voltage limiter.
