Analog to digital converter, encoder, and recorded data reproducing apparatus |
摘要 |
An encoder for an A/D converter includes a plurality of ROM cells connected between bit lines and word lines. Each of the ROM cells is responsive to a word line select signal supplied to a word line associated with each of the ROM cells for supplying a digital output signal according to the word line select signal to a bit line associated with each of the ROM cells. A logic processor is coupled to one of the bit lines and to two of the word lines used to select a ROM cell connected to the bit line. The logic processor produces an output signal indicative of a selection of the ROM cell connected to the bit line, based on word line select signals supplied on the two word lines.
