Abstract
A method and circuit for implementing low duty cycle distortion and low power differential to single ended level shifter, and a design structure on which the subject circuit resides are provided. The circuit includes an input differential amplifier providing positive and negative differential amplifier output signals coupled to an output amplifier providing a single ended output signal. The output amplifier amplifies and inverts the negative differential amplifier output signal. The output amplifier amplifies and superimposes the positive differential amplifier output signal with the amplified and inverted negative differential amplifier output signal, providing the single ended output signal with low duty cycle distortion.
