In one embodiment the differential input of the equalizer is fed to a switch that interchanges the complementary signals at the differential input, changing the sign of the received signal, at each transition of a clock at the Nyquist frequency. The switched signal is filtered by a low-pass filter with positive feedback enhancement at DC gain and digitized by a sense amplifier, and the digital output of the sense amplifier is inverted during every half-cycle of clock at the Nyquist frequency, restoring the sign of the input signal."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Positive feedback enhanced switching equalizer with output pole tuning","description":"A switched equalizer for equalizing the frequency response of a channel with high-frequency attenuation.
