摘要： A magnetic disk system which records and reproduces data on a magnetic disk at different data transfer rates depending on a track position on the disk includes a transversal waveform equalizing circuit which implements an optimal waveform shaping for a readout waveform. The waveform equalizing circuit consists of a register, a frequency synthesizer, a PLL, and a transversal circuit. The transversal circuit consists of variable delay circuits, variable gain amplifiers, and an adder. The frequency synthesizer produces a write clock signal having a frequency which corresponds to a value stored in the register which depends on the data transfer rate, and the PLL responds to the write clock signal to produce a control signal by which the delay time of the transversal circuit is controlled. Consequently, the delay characteristic is not affected by disparity of circuit components of the transversal circuit, and the write clock frequency and the delay time of the transversal circuit can be set to intended values by merely changing the value stored in the register in response to a variation of the data transfer rate.

摘要： A semiconductor device includes an MOS field effect transistor having a structure in which the tops of its source/drain regions are covered with a polycrystalline silicon layer. The impurity concentration distribution in its depth direction of the source/drain regions of the MOS field effect transistor is such that the concentration is sufficiently high in an area necessary to have conductivity a prescribed depth away from the surface of the semiconductor substrate, and the impurity concentration drastically decreases in areas deeper than that. Thus, a punch through phenomenon in positions relatively deep in the channel region is suppressed, and an MOS field effect transistor having its channel length reduced to 0.5 .mu.m and less and achieving high performance can be obtained. Such an MOS field effect transistor can be produced by implanting an impurity a number of times, controlling appropriately the peak value and the peak position of the impurity concentration, before and after or only after the formation of the polycrystalline silicon layer.

摘要： By making a folded waveform of a folding circuit sharp, the number of elements used in an ADC is reduced and less power consumption is achieved. A folding circuit is composed of a plurality of master-comparator latches, a pair of wiring means for master-to-slave connection, and a slave latch. By means of the wiring means, the non-inverted outputs and the inverted outputs of the master-comparators latches are alternately drawn in the order of magnitude of reference voltages, superimposed, and fed into a pair of inputs of the slave latch. A Gray code signal is directly encoded by an encoder according to the output of the slave latch. A folded signal, which is the output of the folding circuit, takes a sharp waveform. The number of slave latches can be reduced. No XOR gates are required.
