Abstract
A cost-effective, low power and low distortion digital data line driver is disclosed with the capability to operate from a limited voltage source while maintaining wide output voltage swings. The line driver has the noise immunity attribute of a fully differential input device without all the usual complex CMFB circuitry normally required. The line driver provides a low distortion output with a low output impedance and maintains its impedance value on the same order of magnitude at frequencies up to four times the Nyquist rate.
