ABSTRACT:
An operational amplifier for canceling an offset and continuously generating an output signal. The operational amplifier includes a first operational amplification unit and a second operational amplification unit each having at least one electrical characteristic that is substantially the same as one another. One of the operational amplification units performs a canceling operation (holding operation and compensation operation) of the offset voltage while the other operational amplification unit performs a non-canceling operation and generates the output voltage by amplifying an input voltage. Both operational amplification units alternately perform the canceling operation and the non-canceling operation.
