专利汇可以提供Analog to digital converter专利检索,专利查询,专利分析的服务。并且PURPOSE:To suppress the noise of a sampling pulse source mixed into a digital output signal by integrating a parallel processing type A/D converter by adding a frequency dividing circuit which divides an A/D conversion pulse from the sampling pulse source by N. CONSTITUTION:When the frequency of a sampling pulse source connecting with the A/D conversion pulse input terminal 12 of a parallel processing type A/D converter is NfS and phase noise power spectrum density S (f), the output frequency of an integrated N-frequency-dividing circuit 18 is fs and its noise spectrum density is S (f)/N. Pulses with the frequency fS are applied to a comparator group 15 to sample an analog input signal Vin. During the sampling, a noise from the sampling pulse source is added to the signal Vin, but its level is S (f)/ N, thereby suppressing the mixing of the noise into the signal Vin to 1/N.,下面是Analog to digital converter专利的具体信息内容。
