    摘要: A semiconductor device carries out a test utilizing contact with a probe needle without being affected by narrowing of the pitch at which output pads are arranged. The device is equipped with test circuits provided between a plurality of output buffers via which signals are output and output pads corresponding thereto. The test circuit includes output switches caused to sequentially make connections by a controller in test and interpad switches involved in making connections of the output pads with a test pad by the controller in test. In test, probe needles are brought into contact with the test pad. The output pads are not used in test, and can be arranged at a narrowed pitch. Thus, the chip area can be reduced and are therefore so that the pitch for the output pads can be narrowed and the chip area can be decreased.

    摘要: An operational amplifier capable of offset cancel in a shorter period, as well as a line driver capable of shortening one horizontal period and a liquid crystal display device are provided. In the operational amplifier of the invention, a time necessary for feed back control can be shortened than usual by a constitution that an output voltage VO in one horizontal period H1 which is one horizontal period before is defined as a reference voltage in an offset cancel preparatory period HC2, thereby changing the output voltage VO(2) only by the offset voltage VO(2) by the feed back control. In the line driver of the invention, the operational amplifier not used for the output of display data D1 to D6 conducts offset cancel operation and it is successively shifted on every one horizontal period. Since it is no more necessary to incorporate the offset cancel preparatory period in the output period, one horizontal period can be shortened further.

    摘要: An offset cancel circuit for an operational amplifier comprises a capacitive element for storing a voltage to be amplified by an operational amplifier section and containing an offset, and for feedback-controlling a voltage value of the operational amplifier section based on the stored voltage, and switching elements for switching operation between the storage of the voltage in the capacitive element and the feedback control based on the value of the voltage stored in the capacitive element. The capacitive element and the switching elements can be used to cancel accurately an offset in the operational amplifier section without increasing the gate areas of transistors in the operational amplifier section.
