摘要： A detector obtains an output signal from an input signal containing a target signal and outputs the output signal. The detector includes an amplifier configured to receive the input signal and the output signal, compare the input signal to the output signal to output a comparison result; an envelope generator configured to weight a first value and a second value having a sign opposite to that of the first value in accordance with the comparison result, integrate the weighted first value and the weighted second value, and output an integration result as the output signal; and a controller configured to control the envelope generator in accordance with the input signal. The controller controls the envelope generator to mitigate an increase in an absolute value of the integration result when the input signal contains a frequency component other than a frequency component of the target signal.

摘要： In performing calibration, a control circuit in a calibration circuit of an interface circuit controls a selector so that voltages V1, VREF or voltages V1, V2 are applied to a comparator. The two voltages input to the comparator is switched between positive and negative inputs of the comparator. In both of the states, the control circuit obtains signal values of variable-resistor control signals UPCODE, DNCODE at a time when an output of the comparator is changed, and obtains calibration data to control the resistance value of the terminating resistor by using a mean value of the obtained signal values.
