The invention discloses a level conversion circuit which is electrically connected between a level input end and a level output end and used for converting a first voltage domain level signal input bythe level input end into a second voltage domain level signal and outputting the second voltage domain level signal to the level output end. The level conversion circuit comprises a control module, aconversion module and a processing module, and the control module is used for receiving a first voltage domain level signal input by a level input end and outputting a corresponding pulse electric signal to the conversion module according to the first voltage domain level signal. The conversion module receives the pulse electric signal and generates a corresponding second voltage domain level signal to the processing module according to the pulse electric signal. The processing module is used for processing the second voltage domain level signal and transmitting the processed second voltage domain level signal to the level output end. Therefore, the level conversion speed can be improved, and the power consumption is low.
Description
technical field [0001] The invention relates to the field of integrated circuits, in particular to a level conversion circuit. Background technique [0002] In an integrated circuit chip, voltage domain inconsistencies often occur between circuit modules, so level conversion circuits are required for communication between modules. In the prior art, in the process of level signal conversion, in order to achieve a faster conversion speed and meet lower transmission delay requirements, there is usually a problem of high power consumption. Contents of the invention [0003] In view of this, it is necessary to provide a level shifting circuit capable of high-speed level shifting and low power consumption. [0004] The technical scheme that the present invention proposes for reaching above-mentioned purpose is as follows: [0005] A level conversion circuit, electrically connected between the level input terminal and the level output terminal, for converting the first voltage ...
