摘要
A sampling circuit samples an input signal by using at least one switch, at least one capacitor, an amplifier, and a clamp block connected between an output terminal and a negative input terminal of the amplifier. The clamp block prevents a difference between a voltage level of the output terminal of the amplifier and a voltage level of the negative input terminal of the amplifier during sampling from exceeding a maximum voltage difference.
