1. An electronic circuit which converts a receive signal being analog into reception data being digital, the electronic circuit comprising:
a delay circuit configured to receive a first receive signal and to output a reference signal, the reference signal being generated by delaying the first receive signal as much as one of a plurality of different timing delays respectively set to a plurality of loops;
a sampler configured to receive a second receive signal and to sample the second receive signal based on the reference signal in each of the plurality of loops;
a timing skew estimation circuit configured to output a compensation signal for compensating for a timing skew by determining a metric value indicating a statistical characteristic of a plurality of sample data sampled through the sampler and estimating the timing skew based on the determined metric value; and
a controller configured to control an operation of the timing skew estimation circuit,
wherein the timing skew estimation circuit includes:
a metric calculator configured to calculate the metric value indicating the statistical characteristic of the plurality of the sample data;
an accumulator configured to accumulate the metric value; and
decision logic configured to estimate the timing skew based on an output value of the accumulator.
