Abstract

See full text

A binary receiver combines a fast amplifier with a relatively slow amplifier for noise rejection. Both the fast and slow amplifiers employ hysteresis. The fast amplifier has relatively lower hysteresis, meaning that its sensitivity is a less effected by prior data values but more susceptible to glitch-induced errors. Conversely, the slow amplifier has relatively higher hysteresis and rejects glitches but introduces undesirable signal-propagation delays. A state machine taking input from both amplifiers allows the receiver to filter glitches without incurring a significant data-propagation delay.
