Abstract :
Differential amplifiers respond with increasing phase difference between both outputs, when driven single-ended at high speed. A novel asymmetrical delay-line between two stages was integrated to compensate this effect. Measurements show significant less spread in group-delay over operation bandwidth. From this, less jitter can be expected.
