Abstract

The invention discloses a multiphase set digital sine wave generator which comprises a clock delay module, a plurality of counting sequence generators, a multiphase register, a sine wave meter reading module and a plurality of data gating modules. Different clock signals generated by the clock delay module are utilized to control the multiphase register and the data gating modules to carry out data collection or screening, the effect of outputting multiple different sine wave signals is achieved, the sine wave generator serves as an integrated device, the functions of multiple original independent signal generators are completed, moreover, the phase difference between different sine wave signals can be stably maintained, the number of used devices is greatly reduced, and the integration level of the devices is improved. Correspondingly, the invention also discloses an integrated circuit with the same beneficial effects.

Description

technical field [0001] The invention relates to the field of signal generators, in particular to a polyphase set digital sine wave generator and an integrated circuit. Background technique [0002] At present, sine wave signals are widely used in motor drive, signal communication and other fields. With the development of circuit integration, the demand for sine wave signals in the circuit is increasing, and a circuit structure may require multiple sine wave signals with different phases. In order to obtain these sine wave signals of different phases, the existing scheme is usually to set up a plurality of independent sine wave generators, and each sine wave generator generates a sine wave signal of a specific phase. This method requires more Hardware cost and space cost. [0003] Therefore, how to provide a solution to the above technical problems is a problem that those skilled in the art need to solve. Contents of the invention [0004] In view of this, the object of ...
