摘要： The same analog signal is inputted to an 8-bit AD converter and to a 4-bit AD converter to obtain an 8-bit digital data and a 4-bit digital data for the same sample value of the analog signal. Values of the 8-bit digital data and 4-bit digital data are compared with each other. The 8-bit digital data is outputted as a digital signal for the sample value of the analog signal when a difference between these values is not greater than one-half the quantity that corresponds to the least significant bit of the 4-bit digital data, and the 4-bit digital data is outputted as a digital signal for the sample value of the analog signal in other cases. There is realized AD conversion which operates apparently at high speeds maintaining high accuracy.

摘要： A parallel (flashed) type analog-to-digital converter is provided which is fabricated on a single integrated-circuit chip. An input analog voltage is compared with respective reference voltages by a number of comparators. A change position of an output pattern (for example, a thermometer format signal) of the comparators is detected by a number of exclusive OR circuits. The exclusive OR circuits are grouped into several groups, and in each group, the output transistors of respective exclusive OR circuits are connected to separate bit lines. Several sets of separate bit lines are connected to one set of output bit lines through emitter followers or diodes so that parasitic capacitances related to the output transistors are reduced.

摘要： An integral-type small signal input circuit having a Miller integrator is adapted to perform cyclically an integrating operation, a resetting operation and an input offset current compensating operation. An input offset current compensation circuit which forms a feedback circuit of the amplifier in the Miller integrator is arranged to supply a compensation current to the amplifier for canceling the input offset current during the compensating operation and to supply the held compensation current to the amplifier during the integrating operation. During the compensation period, a low-pass filter which blocks sinusoidal noise components in the input signal is connected to the input of the integrator so that the held compensation current is not affected by the noise components.
