A/d converting circuit
专利汇可以提供A/d converting circuit专利检索，专利查询，专利分析的服务。并且PURPOSE:To realize a high-speed operation of an A/D converter with simple constitution, by combining a delta modulating circuit and an up-down counter. CONSTITUTION:When both input and output of a D-FF7 are set at H, i.e., the output -Q of an FF3 is held at H consecutively for >=2 cycles of a clock pulse, the output of an AND gate 8 is set at H. And the contents of an up-down counter 10 are counted up. When both the input and output of the FF7 are set at L, the output of a negative logic NAND gate is set at H. Thus the contents of the counter 10 are counted down. In such a way, it is possible to produce the analog voltage information at the counter 10 in the form of digital value by counting up or down the contents of the counter 10 as long as H or L is continuous with each clock cycle. In addition, a high-speed operation is possible since the up-down counting is carried out with each cycle for the response to a change of input voltage.，下面是A/d converting circuit专利的具体信息内容。
