    摘要: A gate electrode has a relatively long gate length of e.g., about 10 &mgr;m. In a region immediately above the gate electrode which is sandwiched between first-layer metals provided is a metal dummy pattern having a width in the first direction and extending in the second direction perpendicular to a direction of gate length (direction of current flow). Moreover, a geometric center of the metal dummy pattern in the second direction is equal to a geometric center of the gate electrode in the second direction. This maintains the symmetry in shape of the metal dummy pattern as viewed from the gate electrode. Such a structure can make deterioration in characteristics of a plurality of elements uniform while maintaining the essential effect of a metal CMP.

    摘要: Disclosed is a high-speed A/D converter (15) including an improved differential amplifier circuit. Each comparator (61) provided in the A/D converter directly receives a complementary or differential analog input voltage to be converted. A differential amplifier circuit provided in each comparator compares an applied analog input voltage difference and an applied reference voltage difference. A binary signal indicative of a comparison result is applied to an encoder (4) through a binarization circuit. An analog input voltage which is not to be converted is directly applied to the comparator, that is, to the differential amplifier circuit through none of resistor elements and components, whereby conversion time delay is prevented.

    摘要: In a controlled threshold type electric device having first and second transistors and a differential amplifier which receives a reference input voltage, a voltage corresponding to the threshold voltage of the first transistor itself is applied to the differential amplifier as a feedback input voltage. The differential amplifier compares the received feed back input voltage with the reference input voltage and applies a control voltage to the backgate of the first transistor so that the threshold value of the first transistor converges to a desired value. This control voltage is also applied to the backgate of the second transistor so that the threshold voltage of the second transistor also converges to a desired value. Since the voltage corresponding to the threshold value of the first transistor is applied to the differential amplifier, an accurate feed back control is made. Further, since the differential amplifier can be manufactured through the MOS standard process, the manufacturing cost can be reduced.

    摘要: A ladder resistance (1) consisting of resistance elements (r1, r2, . . . , r8) connected in series with intermediate taps (T1, T2, . . . , T7) interposed is so arranged as to be folded back at its midpoint. Pairs of differential comparators (C1 and C7, C2 and C6, . . . ) which are connected to common intermediate taps are each disposed adjacently so as to be nearest to the intermediate tap to be connected thereto. Accordingly, wires connecting the differential comparators (C1, C2, . . . , C7) to the intermediate taps (T1, T2, . . . , T7) become shorter and an area of a semiconductor chip needed for arranging the wires can be reduced. Thus, reduction in area of the semiconductor chip needed for providing the device therein is achieved.

    摘要: In order to obtain a constant current circuit which has an excellent constant current property and requires no plural bias circuits, a base of an NPN bipolar transistor (5) and a gate of an N-channel MOS transistor (6) are connected to a first terminal (1) in common. A collector of the transistor (5) is connected to a second terminal (2) and a source of a transistor (6) is connected to a third terminal respectively, while a voltage source (59) is connected between the first and third terminals. An emitter of the transistor (5) is connected with a drain of the transistor (6). Identical bias voltages are supplied to the base and the gate, while a gate-to-drain voltage of the transistor (6) is equal to a base-to-emitter voltage of the transistor (5). Thus, the transistor (6) operates in a pentode region, to serve as a constant current load for the transistor (5).

    摘要: Positive and negative output ends of a differential circuit in a sample hold circuit are connected to capacitors through switch circuits. Further, collectors of two input transistors of a buffer circuit connected to the sample hold circuit are driven by a collector driving differential circuit, so as to make the collector.multidot.base voltages of two input transistors same to each other. Consequently, a stable sample hold circuit having an arbitrary gain can be provided. In addition, drifts of outputs from two capacitors in the sample hold circuit can be made equal to each other by the buffer circuit.
