  • Techniques for adjusting level shifted signals
    Patent number: 7884644
    Abstract: A level shifter circuit includes first and second transistors that receive a first input signal at control inputs. A level shifted output signal is generated by the first and the second transistors. Third and fourth transistors receive a second input signal at control inputs. The first input signal is an inverse of the second input signal. A first multiplexer circuit is configurable to couple a control input of a fifth transistor to the first and the second transistors. A second multiplexer circuit is configurable to couple a control input of a sixth transistor to the third and the fourth transistors.
