Abstract

The invention provides a grouping pseudo random rotation thermometer decoding circuit comprising a D-trigger module which is used for data transmission; a connection module which is used for performing binary weight distribution on data outputted by the D-trigger module and generating a thermometer code with binary weight and is connected with the D-trigger module; and a randomizer which is used for performing randomized rotation processing on the thermometer code outputted by the connection module and is connected with the connection module. According to the grouping pseudo random rotation thermometer decoding circuit, conversion speed and precision of a digital-to-analog converter can be enhanced. Meanwhile, the circuit design is simple in structure so that area of the decoding circuit can be reduced.

Description

technical field [0001] The invention relates to the field of digital-analog hybrid integrated circuit design, in particular to a grouped pseudo-random rotary thermometer decoding circuit that can be used in a digital-to-analog converter. Background technique [0002] With the continuous development and progress of communication technology, the ability of communication system to process signals is also continuously improved. One of the most important functions of signal processing is converting between analog and digital signals. As one of the key modules of communication equipment, the analog-to-digital converter has increasing requirements on its speed and accuracy. [0003] Current steering digital-to-analog converters are widely used in high-speed and high-precision communication systems because of their good compromise in layout area, resolution and conversion rate. [0004] Current steering digital-to-analog converters can be mainly divided into: binary code weighted ...
