Waveform compensation circuit
专利汇可以提供Waveform compensation circuit专利检索，专利查询，专利分析的服务。并且PURPOSE:To reduce peak shift without deteriorating a signal-to-noise ratio, by providing a compensation quantity detection circuit which inputs a peak detecting window pulse and a peak detecting pulse and outputs the potential of waveform compensation as a compensation quantity, and performing the waveform compensation without deteriorating the amplitude of a read waveform. CONSTITUTION:The titled circuit is constituted of a peak detecting window pulse generation circuit 7, a peak detection circuit 8 to output the peak detecting pulse F which becomes true when detecting the peak of a readout signal in a state where the peak detecting window pulse J is true, a compensation quantity detection circuit 9 which detects a time interval from a time when the peak detecting window pulse J becomes true to the time when the peak detecting pulse F becomes true, and the time interval from the time when the peak detecting pulse F becomes true to the time when the peak detecting window pulse J becomes false, and outputs a time difference between them as the compensation quantity, and a phase compensation circuit 13 which changes the delay quantity of the peak detecting pulse F corresponding to the compensation quantity within a prescribed range and outputs it as a compensated peak detecting pulse F, etc. In such a way, it is possible to reduce the peak shift without deteriorating the signal-to-noise ratio.，下面是Waveform compensation circuit专利的具体信息内容。
