An improved low voltage to high voltage translator for digital electronic circuits
providing reduced rise times, fall times and transition times that remain independent
of operating conditions. This is accomplished by modifying a conventional low-to-high
voltage translator to include a switched active pull-up at the output of the first
high-voltage switch, controlled by the input low-voltage signal and gated by the
output from the low-to-high-voltage translator and a switched active pull-down
at the output of the first high-voltage switch, controlled by the input low-voltage
signal and gated by the complement of the output from the low-to-high-voltage translator,
so as at to provide regenerative pull-up and pull-down that also counteracts the
bootstrap capacitance at the output of the first high-voltage switch.
