    • An operational amplifier with two pairs of differential inputs for use with an input switch capacitor network. The operational amplifier has reset devices for resetting the second pair of differential inputs while amplifying the first pair of differential inputs, and for resetting the first pair of differential inputs while amplifying the second pair of differential inputs for reducing memory effect in electronic circuits. In an embodiment, the amplifier has an additional reset device for resetting the outputs during a prophase of amplifying the first pair of differential inputs and a prophase of amplifying the second pair of differential inputs.
    • 具有两对差分输入的运算放大器,用于与输入开关电容网络一起使用。 运算放大器具有复位装置,用于复位第二对差分输入,同时放大第一对差分输入,并用于复位第一对差分输入,同时放大第二对差分输入,以减少电子电路中的记忆效应。 在一个实施例中,放大器具有用于在放大第一对差分输入的前期期间复位输出的附加复位装置以及放大第二对差分输入的前期。
