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.

Creation Instructions (丨) The present invention relates to an analog-to-digital converter, especially a high-speed, high-resolution analog-to-digital converter with a dual-track folder. The structure is simple and high Reliability, can eliminate the phenomenon of signal flicker, and increase the number of bits divided by each cell to improve the signal processing speed and signal quality. Central Government Bureau of the Ministry of Economic Affairs, Consumer Affairs Cooperation, Du Yinzhuang (#Please read the notes on the back and fill in this page) Custom analog to digital converter, use the folder and comparator to convert the analog input signal into digital data. Referring to FIG. 1, a general folder structure, taking folded waves folded as an example, includes eight pairs of CMOS differential pairs, in which a CMOS element of each CMOS differential pair is gated to the input terminal of the input signal Vin, and the other One input terminal respectively inputs Vrefl, Vref2, ~ Vref9, which are generally equally spaced voltage dividers. The CMOS drains of each CMOS differential pair are connected in parallel to form Vout +, and the other CMOS drains are also connected in parallel. Vout · is formed, and Vout = Vout, Vout-. Figures A and B show the folded waves of the folded two, folded four, and folded eight, respectively, and the corresponding bit chirp. The curve F8 in Fig. 2A is the conversion function of the folded wave. If only Vref2, Vref4, Vref6, and Vref8 are used, the curve F4 of A in Fig. 2 is obtained, that is, a folded wave folded in four. Similarly, if only Vref4 and Vref8 are used, the curve f2 of the folded wave folded in Fig. 2A is obtained. If the above-mentioned F *, F4, F2 are taken out of the high and low levels by the comparator, that is, the digital signal, the three high-bit data shown in Figure 2B are obtained, B8, B7, B ,. The sample holder is used to extract the analog input signal, and the output signal of the sample holder is converted into a folded wave signal by a folder, and then a plurality of paper scales are used in China (CNS) grid (210X297!). The Ministry of Economic Affairs Central Standards Bureau ’s Consumer Cooperative Cooperative Printing Co., Ltd. 443038 C7 _ D7 Five 'Creation Instructions (1) Take out digital data from a comparator, and this converter is a nine-bit flash high-speed analog-to-digital converter. A total of 512 comparators are required. In addition, although the comparator can be used to convert the folded wave of folded two, folded four and folded eight into three high-bit data, unfortunately, the state of 'high three-bit data (U8, U7, U6) does not change. 'Identical' can cause temporary errors and misinterpretations of signals. The conventional analog-to-digital converter requires a large number of amplifier buffers, and the low-bit processor needs to use four sets of folded waves, while the high-bit requires eight flash comparators, which requires more chip area and more complicated circuits. , The reliability of the overall circuit is low. The conventional analog-to-digital converter uses analog averaging to correct the DC error caused by the equivalent resistance (R) in the interpolation block. Therefore, additional circuits are required and more chip area is occupied. In addition, the conventional analog-to-digital converter only allocates one bit for each cell, which has low efficiency and cannot greatly improve the signal processing speed. Further, if the conventional analog-to-digital converter does not include a bit synchronization circuit, it will cause error codes and reduce the quality of the output signal. Therefore, there is a great need for a high-speed, high-resolution analog-to-digital converter with a simple structure and high reliability, which can eliminate signal misunderstanding and increase the number of bits per cell to increase the speed of signal processing. The main purpose of the present invention is to provide an analog-to-digital converter, which uses an folder and a comparator to convert the input analog signal into digital data.

In addition, the five-bit 値 is fed back to the grid selector to select the correct grid side K, K + 1, K + 16, and K + 17 phase-shifted waves, and then use a flash comparator to compare the K + 1 6th phase, the middle 値 between the K + 1 and K + 1 phases (or K + 1 6 phase) Compared with the middle 値 of the K + 1 7th phase and the K + 1 of the 7th phase), with simple logic The least bit is calculated. Finally, after the nine bits are overloaded, the correct digitized data is read by the latch.

For a converter with nine-bit resolution, three high-order bits, five middle-order bits and one Low-level digital data can be implemented using only 35 comparators, compared with 5 1 2 comparators in conventional technology, which greatly reduces the number of components, thereby simplifying the overall architecture, improving the reliability of the circuit, and further reducing Power consumption. In the last stage of the present invention, a high-speed flash comparator is used to greatly expand its scalability. This embodiment uses only a one-bit flash comparator, as long as the signal is amplified by ten or more before entering the flash comparator.

However, The corresponding inputs of U8, U7, and 116 state transitions are different. This will result in an error code. Therefore, this system uses a dual-track reading method to eliminate this phenomenon by using double sets of folding and simple logic circuits. There is only a slight logical delay between the reading time and the original time, and it is almost an instant signal. The description of the above dual-track reading method is as follows: Referring to FIG. 4, a data chart of the dual-track reading according to the present invention.
