Abstract
A filtering module filters out high frequency signals, primarily noise, from an input data stream. The filtering module includes an input module, a phase detecting module, and a threshold module. The input module performs either a charging or a discharging across a capacitor on a basis of an RC time constant. The phase detecting module is coupled to the input module to keep identical phase at a first node and an output node. The threshold module is coupled to the phase detecting module for providing an output signal based on a threshold voltage and the charging or the discharging across the capacitor.
