Abstract: An electronic circuit converts a receive signal being analog into reception data being digital. The electronic circuit includes a delay circuit that receives a first receive signal and outputs 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 that receives a second receive signal and samples the second receive signal based on the reference signal in each of the plurality of loops, a timing skew estimation circuit that outputs a compensation signal for compensating for a timing skew by extracting a statistical characteristic of a plurality of sample data sampled through the sampler and estimating the timing skew based on the statistical characteristic, and a controller that controls an operation of the timing skew estimation circuit.
