Abstract
A digital waveform conditioning circuit includes a noninverting amplifier stage. A source of digital information is coupled to the input of the amplifier via a series resistor. The amplifier output is coupled to a digital utilization circuit. A feedback capacitor is coupled between the amplifier input and output terminals to provide integration of unwanted input noise pulses, positive feedback during threshold transitions for fast rise and fall times, and a hold-off voltage for a specified time thereafter to prevent oscillations during said transitions.
