Abstract
A differential input/differential output converter circuit. The circuit comprises differential complementary input modules each comprising cross-coupled devices for biasing current mirror masters to a condition that increases the operating speed in response to a transition in the differential input signals. Certain current mirror masters are biased to a strong threshold condition and other current mirror masters are biased to a weak threshold condition responsive to a state of the differential input signals. According to another embodiment, the converter circuit further comprises a boost circuit capacitively coupled to the converter circuit for providing further speed improvements.
