  • Patent number: 11855652
    Abstract: A multiplexer (MUX) calibration system includes main MUX circuitry, first replica MUX circuitry, digital-to-analog (DAC) circuitry, detection circuitry, and control circuitry. The main MUX circuitry receives clock signals and outputs a first data signal based on the clock signals. The first replica MUX circuitry receives the clock signals and outputs a second data signal based on the clock signals. The DAC circuitry generates an offset voltage. The detection circuitry receives the second data signal and the offset voltage and generates a first error signal based on one or more of the second data signal and the offset voltage. The control circuitry receives the first error signal and generates a first control signal indicating an adjustment to the clock signals.
