Samsung patents equalizer that adjusts signal timing for cleaner data

Samsung has been granted a patent for an equalizer circuit that helps clean up data signals as they travel through a device. It uses a delay circuit and encoding logic to adjust how the signal is split and recombined, ensuring the data arrives accurately.

Why it mattersThis is a routine hardware improvement that helps ensure data integrity in electronic devices, though it does not directly change how users interact with their phones or laptops.

In the filing’s own words

An equalizer includes a delay circuit configured to generate at least one delay signal based on at least one input signal, an encoding circuit configured to generate a plurality of driving signals and a connection switching signal, based on the input signal and the delay signal, a pre-driver configured to generate a plurality of driving switching signals based on the plurality of driving signals, a first differential circuit configured to generate a first differential output signal based on the plurality of driving switching signals, a second differential circuit configured to generate a second differential output signal based on the plurality of driving switching signals, and a connection circuit configured to adjust a connection between the first differential circuit and the second differential circuit based on the connection switching signal.

What exactly they claim (claim 1)

1. An equalizer comprising: a delay circuit configured to generate at least one delay signal based on at least one input signal; an encoding circuit configured to generate a plurality of driving signals and a connection switching signal, based on the input signal and the delay signal; a pre-driver configured to generate a plurality of driving switching signals based on the plurality of driving signals; a first differential circuit configured to generate a first differential output signal based on the plurality of driving switching signals; a second differential circuit configured to generate a second differential output signal based on the plurality of driving switching signals; and a connection circuit configured to adjust a connection between the first differential circuit and the second differential circuit based on the connection switching signal.
