Patent ID: 8004339

Claim:
A level-shifting circuit, comprising: an output circuit comprising: a pull-up circuit coupled to a high-voltage source and configured for pulling up a voltage on an output signal in response to a high-side control signal; and a pull-down circuit coupled in series between a low-voltage source and the pull-up circuit, wherein the pull-down circuit is configured for pulling down the voltage on the output signal in response to a low-side control signal; a high-side inverting buffer operably coupled to the output circuit and configured to drive the high-side control signal responsive to an edge-controlled signal; a low-side buffer configured to drive the low-side control signal responsive to an input signal; and an edge-control buffer including a current minor operably coupled to the high-side inverting buffer, wherein the current mirror is configured to mirror a pull-up control current from one side of the current mirror into the edge-controlled signal, wherein the edge-controlled signal exhibits a slow rise time relative to a fall time of the edge-control signal.
