Abstract
A voltage translation circuit translates an input signal having a first voltage level and a second voltage level to an output signal having the second voltage level and a third voltage level respectively. The voltage translation circuit according to the present invention includes a regenerative circuit having a first terminal and a second terminal. The voltage level at the first terminal increases responsive to the voltage level at the second terminal decreasing. The voltage level at the second terminal increases responsive to the voltage level at the first terminal decreasing. The voltage level at the first terminal defines the output signal. A first switch is coupled to the first terminal of said regenerative circuit, such that closing the first switch decreases the voltage level at the first terminal. A second switch is coupled to the second terminal of said regenerative circuit, such that closing the second switch decreases the voltage level at the second terminal.
