Analog to digital converter with a series of delay units |
July 13, 2010 |
| An A/D converter has a series of M delay units through which a pulse signal is transmitted while being delayed in each delay unit by a delay time depending on a level of an analog signal. A unit of the converter latches the pulse signal outputted from each delay unit at N sampling ti |

Analogue to digital conversion device operable on different sampling clocks |
September 11, 2007 |
| In an A/D conversion device, each delay unit in a pulse delay circuit has inverters INV of m.times.n stages (m, n are positive integers), a clock generator has m-delay lines, and each delay line has inverters INV of i.times.n stages (i=1, 2, . . . , and m). Those delay lines DL1 to DLm |
