Title: Semiconductor integrated circuit
Inventor: YOSHIOKA SHIGEATSU
IPC: H03M1/76
Filed: 1996-12-27
Abstract: PROBLEM TO BE SOLVED: To reduce glitches with minimum area overheads and the increase of an operation speed by selecting a voltage dividing ratio corresponding to the value of input signals and providing a means for outputting a voltage for which the difference voltage of first and second reference voltages is divided by the selected voltage dividing ratio and the means for inhibiting the output for prescribed time. SOLUTION: In an output control circuit, all switches SY1-SY4 are turned OFF for the delay time of a delay element YDL1 from the point of time when the values of the input signals B1 and B2 are changed. During the time, the parasitic capacitor of nodes N1-N4 is charged and discharged and output is started after waiting until charging and discharging are ended and the voltage of a tap communicated to output DAout is stabilized. Thus, the glitches generated by instantaneously changing a tap voltage by the parasitic capacitor of the nodes N1-N4 corresponding to the change of the input signals B1 and B2 are prevented from being outputted. As a result, this semiconductor integrated circuit capable of reducing the all or specified glitches with the minimum area overheads is obtained.

Title: Information recording device
Inventor: SATOMURA SEIICHIRO
IPC: G11B7/00
Filed: 1991-12-16
Abstract: PURPOSE:To ensure an accurate direct verifying operation with no influence of the old data component included in a reproduction signal by recording the phase of a recording clock with a delay secured to the old data on a recording medium based on the phase detection information on the old information. CONSTITUTION:A mask signal S3 is sent to a mask circuit 9 to mask the output of a binarization signal S4 for a fixed time. That is, only a pulse alpha is outputted out of both pulses alpha and beta of the signal S4. Then the pulse alpha is used as a phase information signal of the old data. The output signal S5 of the circuit 9 is sent to a synchronizing clock generating circuit 10 and a clock signal S6 synchronous with the signal S5 is produced. The signal S6 is delayed by a prescribed time by a clock phase correction element 11 and outputted to an encoder 1 as a recording clock signal S7. Thus the pulses alpha and beta can be separated from each other. As a result, an accurate direct verifying operation is attained with no influence of the old component.
