    摘要: A ladder resistor includes a first resistor group including a number of resistors connected in series and generating a number of reference voltages, and a second resistor group including a same number of resistors connected in series as the plurality of resistors included in the first resistor group, and generating a number of reference voltages. The plurality of resistors included in the second resistor group corresponds to the plurality of resistors included in the first resistor group, respectively. Each of the plurality of resistors included in the first resistor group and a corresponding one of the plurality of resistors included in the second resistor group, that is, each resistor pair is symmetric with respect to a given point. The first resistor group is separated from the second resistor group so that they face each other with the point between.

    摘要: A digital-analog converter has unit current source cells each having a differential switch circuit and a constant current source. The differential switch circuit made of two switches is driven by a pair of complementary driving circuits controlled by a bit signal and the inverted bit signal corresponding to that signal and entered simultaneously. The constant current source outputs a constant current to a first and a second current output terminal via the switch circuit. The signals for controlling the driving circuits that drive the switches are such that the delay time for the switch closing operation will be longer than the delay time for the switch opening operation. As a result, the cross point of the two signals to open and close the switches in a complementary manner becomes greater than the median between the maximum and minimum signal levels. That is, even when the threshold value of a currently switching transistor is greater than a median, that value may be arranged to match the median, whereby the furnished switching transistors are not turned on or off simultaneously.

    摘要: A comparator circuit capable of high-speed and accurate operation is disclosed. The comparator circuit includes an amplifier section 4, an inverter 5 connected to the output of the amplifier section 4, and a switching circuit 11 connected across the inverter 5. The amplifier section 4 contains a capacitor 1, an inverter 2 and a switching circuit 3 connected across the inverter 2. Coupled to the input of the amplifier section 4 are switching circuits 8 and 9 for supplying voltages V.sub.1 and V.sub.2 to be compared under timing control. During the first half cycle of comparing operation, the switching circuits 8, 3 and 11 are turned on while the switch circuit 9 is turned off. During the second half cycle of comparing operation, the switching circuit 9 is turned on while the switching circuits 8, 3 and 11 are turned off. The inverter 5, being short circuited by the switching circuit 11, produces a predetermined intermediate voltage during the first half of operating cycle, which is effective to generate voltage outputs accurately and exactly representing the compared results during the second half of the operating cycle.

    摘要: A time interleaved analog-to-digital converter includes a plurality of analog-to-digital subconverters which are monolithically integrated in an array on a semiconductor chip and are sequentially activated into sampling and conversion operation in the time interleaved fashion for converting a received analog signal into a digital form. If an analog-to-digital subconverter in the i-th row of the j-th column of the array is activated at one sampling time in the sequential activation, an analog-to-digital subconverter in the k-th row of the l-th column is subsequently activated, where i, k, j and l bear the relations expressed by:i-2.ltoreq.k.ltoreq.i+2 and j-2.ltoreq.l.ltoreq.j+2.The sequential activation of the analog-to-digital subconverter array assures that the analog-to-digital subconverters disposed in physical proximity to one another are successively activated, thus greatly improving the differential linearity of the analog-to-digital converter characteristics.

    摘要: A reference voltage is divided by a plurality of resistors (6), the respective voltages and an analogue input voltage being compared with each other by comparators (7). An output of each of the comparators is applied to a data transfer circuit (13) of a hand shake type and latched. The data transfer circuit shifts discontinuous portions of logic which appeared in latched data. Therefore, simultaneous selection of a plurality of addresses in an encoder (10) is avoided.

    摘要: A voltage generating circuit, in which the influence of offset of an amplifier on an output voltage is reduced, has first and second bipolar transistors (Q1, Q2) having emitter terminals at the same electric potential. A base terminal of Q1 is disposed on a collector side of Q2. A first resistance element connects the collector side of Q2 with the base side of Q2; and a second resistance element (R1) connects a collector side of Q1 to R2. A third resistance element (R3) connects a base terminal of Q2 with the electric potential of the emitter terminals. An amplifier (A1) outputs a voltage based on a voltage difference between the collector sides of Q1 and Q2; and a voltage-current converting section (MP1, MP2) converts amplifier output into a current supplied to the connection node of R1 and R2. A voltage is then output on the basis of the generated current.
