Abstract

　第１コンパレータ(112a)は、第１電圧信号を所定の閾値と比較し、比較結果に応じた第１二値化信号を出力する。第２コンパレータ(112b)は、第２電圧信号を所定の閾値と比較し、比較結果に応じた第２二値化信号を出力する。第１デジタルサンプリング部(113a)は、第１コンパレータ(112a)によって出力された第１二値化信号をサンプリングすることにより第１サンプリング信号を生成する。第２デジタルサンプリング部(113b)は、第２コンパレータ(112b)によって出力された第２二値化信号をサンプリングすることにより第２サンプリング信号を生成する。位相差検出回路(114)は、第１デジタルサンプリング部(113a)によって生成された第１サンプリング信号と第２デジタルサンプリング部(113b)によって生成された第２サンプリング信号との位相差を検出する。
