Abstract
A novel high-speed phase splitter circuit (100) and method of operation are disclosed. This high-speed phase splitter (100) creates a differential rail-to-rail output signal from a single ended input signal, with an inherent low skew and symmetrical output. The circuit (100) uses a phase splitting input stage (110, 130) followed by several amplification stages (150, 170) that are symmetrical and balanced in nature.
