Patent ID: 7034572

Claim:
A voltage shifting circuit, comprising: a first current path from a voltage supply to ground, the first current path having a first input signal node to which an input signal is coupled and having a pull-up transistor coupled to the voltage supply and a first output signal node from which an output signal is provided, the pull-up transistor having a control node coupled to a first pull-up node, the first current path having a coupling transistor coupled to the first output signal node and a first switching node, the coupling transistor having a control node coupled to the first input signal node, the first current path further having a switching transistor coupled to the switching node and ground, the switching transistor having a control node coupled to the first input signal node, the first current path configured to couple the voltage supply to the first output signal node under control of the first pull-up node and couple the first switching node to ground in response to the input signal; a second current path from the voltage supply to ground, the second current path having a second input signal node to which a complementary input signal is coupled, a second output signal node from which a complementary output signal provided, a second pull-up node coupled to the first switching node, and a second switching node coupled to the first pull-up node, the second discharge path configured to couple the voltage supply to the second output signal node under control of the second pull-up node and couple the second switching node to ground in response to the complementary input signal; and a third current path from the output signal node to ground, the third path configured to couple the output signal node to ground in response to the input signal.
