Abstract

According to some embodiments, a digital switching distortion canceller may receive Ethernet data along with an Ethernet class AB transceiver switching signal. A combiner may combine the output of the digital switching distortion canceller with a digital high switching distortion signal to generate a corrected output signal. According to other embodiments, a switching-signal-to-voltage-converter receives an Ethernet class AB transceiver switching signal and generates a common-mode compensation voltage adjustment. An analog combiner may combine the common-mode compensation voltage adjustment with a noisy common-mode signal to generate a stabilized common-mode voltage. Note that reduction of switching-related distortion might be achieved in the digital domain, in the analog domain, or in both domains according to the embodiments described herein.
