Abstract
A method and apparatus is disclosed for outputting a signal responsive to, and shifted in signal level relative to, an input signal level. A driver includes first circuitry outputting a first signal responsive to an input signal, and second circuitry outputting a second signal responsive to the input signal. The first circuitry includes circuitry for substantially shifting the first signal level relative to the input signal and responds more slowly than the second circuitry. The driver output is responsive to both the first and second signals so that the second circuitry improves driver response.
