Signal and clock recovery comparator circuit

CIRCUIT060072

Overview

The signal recovery circuit is used in digital systems to retrieve distorted clock or data waveforms. These clock and data signals can be attenuated and distorted on long traces due to stray capacitance, stray inductance, or reflections on transmission lines. The comparator is used to sense the attenuated and distorted input signal and convert it to a full-scale digital output signal. A dynamic reference voltage will be connected to the inverting terminal of the comparator which is extracting the common-mode voltage from the input signal.
