Samsung patents method to fine-tune timing in electronic circuits
This patent describes a system that adjusts the timing of electrical signals to ensure they arrive at the correct moment. It uses a detector to find small timing errors and a digital controller to adjust delay lines, which act like adjustable pipes for the signals.
In the filing’s own words
A system and a method are disclosed for generating accurate and programmable phase delay output signals, including a phase detector unit configured to determine a phase disparity signal based on a phase error between outputs of a frequency divider unit cell; a digital calibration logic unit configured to generate a control signal based on the phase disparity signal; and a tunable delay lines unit configured to generate the phase delay output signals based on the control signal.
What exactly they claim (claim 1)
1. A method for generating accurate and programmable phase delay output signals, the method comprising: determining, via a phase detector unit, a phase disparity signal based on a phase error between two or more consecutive phase outputs of a frequency divider unit cell; generating, via a digital calibration logic unit, a control signal based on the phase disparity signal; and generating, via a tunable delay lines unit, the phase delay output signals based on the control signal.
