    Abstract: ADC accuracy is increased by 1 bit by interpolation of comparator outputs in a comparator array, thereby increasing accuracy without significantly increasing power consumption and size. Specifically, an analog-to-digital converter includes a binary converter and a comparator array, which comprises a plurality of comparator blocks, each block having a primary comparator and an intepolating comparator. The intepolating comparator compares an output signal from the primary comparator with a negative output signal from a primary comparator of another block of the plurality of blocks to generate a least significant bit. The binary converter, which is coupled to the array, converts array output to binary code.

    Abstract: The digitization apparatus includes, as a main scale, a pulse delay circuit constituted by a plurality of delay units connected in series or in ring form, a latch/encoder, a circulation number counter, and a latch circuit, and includes, as a vernier, a reverse timing extraction circuit detecting a reverse timing at which any one of the delay units has reversed, and an interpolation circuit. The main scale digitizes a time interval between two successive measurement signals in a resolution equal to a delay time per one delay unit. The vernier digitizes a time difference between a measurement timing indicated by the measurement signal and the reverse timing in a resolution equal to 1/M (M being an integer not smaller than 2). The interpolation circuit includes two delay lines each constituted by a plurality of delay units connected in series or in ring form.

    Abstract: An analog-to-digital data converter converts an input signal to corresponding digital signals. The data converter includes two sets of comparison units arranged in an interlaced sense to alternatively analyze the input signal, generate digital signals corresponding to the result of comparing the input signal and reference signals. Each of the comparison units has a positive output and a negative output, and the digital signal is generated by the negative output and the positive output of the comparison units in a differential way. When the comparison units of one set are performing auto-zeroing, the comparison units of the other set perform the data conversion to generate corresponding digital signals.

    Abstract: A flash EPROM device (100) is disclosed. During a programming operation, a primary programming voltage circuit (116) drives I/O lines (110) to a programming voltage (Vp) according to input data values. Secondary programming voltage circuits (118) are located remotely from the primary programming voltage circuit (116) and further drive I/O lines to Vp in response to the voltage levels on the I/O lines. This arrangement reduces the effect on the load line response of the impedance intermediate the primary programming voltage circuit (116) and the secondary programming voltage circuits (118).

    Abstract: A digital pulse circuit receives parallel N digital signals, assuming N is an even integer equal to or greater than 4, the levels of the signals inverted every time a constant quantity of change in an objective quantity to be measured occurs, any phase differences between the successive signals of the signals about 1/N of the constant quantity; has a logic circuit which enables only two signals which can change state in due process corresponding to the next change of the objective quantity to be measured, to enter the next stage; and synchronizes each of the N digital signals by a clock pulse, to make any phase difference among the N digital signals equal to or more than a predetermined phase difference, and the remove the influence of noise superposed on the digital signals (FIG. 10). In addition, a digital pulse circuit mentioned above; synchronizes each of the N digital signals by a clock pulse; and further synchronizes each of the synchronized signals by the clock pulse, once again; and enables only two signals which can change their states in due process corresponding to the next change of the objective quantity to be measured, among the signals synchronized once, to enter the next stage; and when two of the once-synchronized signals have changed at the same time, maintains the two once-synchronized signals so as not to be synchronized twice, until one of the two signals returns to the state just before the change (FIG. 14).
