    Abstract: An analog-to-digital conversion circuit includes an analog-to-digital converter (ADC) configured to receive an input signal and a first clock signal from an external source and to output a second clock signal and a digital output signal, a decision counter configured to increment a decision count value each time when the second clock signal received from the analog-to-digital converter is applied to the decision counter, a voltage control logic configured to output a control signal based on a result of comparing the decision count value with a reference count value, and a regulator configured to output an operation voltage, wherein the ADC is configured to adjust the cycle of the second clock signal, and the voltage control logic is configured to control the regulator to output a corrected operating voltage via the control signal.

    Abstract: A transmitter includes a data generator, a serializer, a transmission driver and a feedback circuit. The data generator generates a retimed data signal and retimed test data by adjusting a delay amount of each of an input data signal and a test data based on adjusted clock signals. The serializer generates a serial data signal by serializing the retimed data signal based on multi-phase clock signals. The transmission driver generates an output data signal based on the serial data signal and transmits the output data signal through a channel. The feedback circuit detects the setup margin and the hold margin of the retimed test data through a separate path different from a path of the retimed data signal and generates the adjusted clock signals by adjusting delay amounts of the multi-phase clock signals based on the detected setup margin and hold margin of the retimed test data.
