Title: High-speed high-resolution analog to digital converter
Inventor: WANG WEI-JEN
IPC: H03M1/12
Filed: 1998-10-12
Granted: 2001-06-23
Abstract: This invention is about a kind of high-speed high-resolution analog to digital converter, which comprises: a sampling holder; a folder; an equal-phase deviator; plural comparators; an encoder; a clock generator; a high bit dual-rail type folding processor; a flash comparator; a fine grid selector; an encoder; and a latch apparatus. The sampling holder takes out the analog input signal. The folder will convert the output signal of the sampling holder into the folding waves, in which each of the folding waves has two sets of double-folded, quad-folded, and octal-folded waves. The two sets of double-folded and quad-folded waves are sent to the high bit dual-rail type folding processor, and two sets of octal-folded waves are sent to the equal-phase deviator. The high bit dual-rail type folding processor will generate three high bit data. The equal-phase deviator will make the octal-folded waves deviate for thirty one times, each deviating 11.25 DEG, so as to generate thirty-two folded waveforms for the nine grid selector. After passing through the fine grid selector, the thirty-two comparators are used to digitize these thirty-two folded waveforms at the same time such that the digitized data is then encoded into middle-sectional five-bit data through the use of the encoder. By feeding back this five-bit data to the fine grid selector, an accurate fine grid is selected for the flash comparator. The flash comparator compares the middle value of the K phase and the K+1 phase with the K+16 phase value, or compares the middle value of the K+16 phase and the K+17 phase with the K+1 phase value such that the smallest bit is obtained through a simple logic operation. Finally, after these nine bits are undergone with overflow treatment, accurate digitized data is read from the latch apparatus. Therefore, by using flash, folding deviation, and the converting technique of section division and time division, the input signal is quickly converted into digital signal. In particular, by using the dual-rail type folding processor to obtain high bit data, the twinkling phenomenon is eliminated and signal quality is raised. In addition, the whole circuit has a smaller chip area and a lower power consumption such that it is suitable for the application of video frequency.

The matrix circuit 5 generates primary colors faithful to the component video input signals of various of various incoming television systems.
