Samsung patents receiver that tunes signal clarity using adjustable parts
Samsung describes a data receiver that improves signal quality by adjusting internal electrical components. It uses a circuit to tweak resistor and capacitor values so that the signal matches specific target levels, helping to reduce interference during data transmission.
In the filing’s own words
A receiver includes a CTLE circuit configured to generate an equalization signal by performing first equalization on a received signal based on a first source resistor and a first source capacitor, an ADC configured to sample the equalization signal and generate a plurality of sampling symbols, a decision feedback equalizer (DFE) configured to generate a plurality of estimated symbols corresponding to the equalization signal by respectively subtracting residuals of previous sampling symbols from the plurality of sampling symbols, and a parameter adjustment circuit configured, in a first cycle based on the plurality of estimated symbols, to adjust the first source resistor such that a value of a first post tap converges to a first preset value and to adjust the first source capacitor such that a value of a second post tap converges to a second preset value. The first post tap and the second post tap are different.
What exactly they claim (claim 1)
1. A receiver comprising: a continuous time linear equalizer (CTLE) circuit configured to generate an equalization signal by performing first equalization on a received signal based on a first source resistor and a first source capacitor, the first source resistor and the first source capacitor being adjustable; an analog digital converter (ADC) configured to sample the equalization signal and generate a plurality of sampling symbols that are continuous and correspond to the equalization signal; a decision feedback equalizer (DFE) configured to generate a plurality of estimated symbols corresponding to the equalization signal by respectively subtracting residuals of previous sampling symbols from the plurality of sampling symbols; and a parameter adjustment circuit configured, in a first cycle based on the plurality of estimated symbols, to adjust the first source resistor such that a value of a first post tap converges to a first preset value and to adjust the first source capacitor such that a value of a second post tap converges to a second preset value, the second post tap and the first post tap being different.
