摘要：
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.
