Patent ID: 8823440

Claim:
A level shifting circuit with dynamic control, comprising: a dynamic controller, outputting a dynamic voltage and an output data signal; a level shifter, controlled by the dynamic controller, comprising an input signal receiver, an output signal generator and a bias current controller, coupled in series between a ground voltage and a high level voltage, wherein the input signal receiver receives the output data signal from the dynamic controller, and the output signal generator generates a level-shifted data voltage signal, wherein the bias current controller is controlled by the dynamic voltage and is at a first current-output capability when the level-shifted data voltage signal is at a stable stage and is at second current-output capability when the level-shifted data voltage signal is at an unstable stage, wherein the level-shifted data voltage signal at the stable stage has a constant data voltage of the ground voltage or the high level voltage and the level-shifted data voltage signal at the unstable stage has a voltage level in changing but not reaching to the constant data voltage level yet, wherein the first current-output capability is greater than the second current-output capability but the second current-output capability is still in operation greater than zero capability.
