Abstract: A fast gain-dependent mix DC offset calibration circuit includes: a DC offset calibration controller, a mix DC offset calibrator, and a digital-domain DC offset calibrator. The DC offset calibration controller is configured to output a first control signal to start the mix DC offset calibrator based on state information sent by a state controller of the zero-IF receiver. The mix DC offset calibrator is configured to execute a mix DC offset calibration algorithm to perform mix DC offset calibration and obtain a calibration codeword when the first control signal is at a first value. The digital-domain DC offset calibrator is configured to execute a digital-domain DC offset calibration algorithm when the first control signal is at a second value, and perform digital-domain DC calibration based on the calibration codeword.

Abstract: The present invention provides a high temperature and bright red ink-jet ink for ceramic decoration, its preparation method and application thereof. On the base that the existing ink-jet ink production process, ink-jet printing equipment and ink-jet printing process are not made major changes, high temperature bright red ink basic glaze powder composition, basic glaze frit powder composition, solvent composition, basic glaze powder and bright red pigment grinding method and particle size optimization, ink composition and processing methods are adjusted and optimized. Thus the performance of high temperature bright red ink can meet the requirement of the use of ink-jet printing machine, and after high temperature firing (1080° C.˜1230° C.), the surface decoration color of ceramic tile sprayed a single printed high temperature bright red is bright red, colorful, pure red, and at the superposing place with other color ink-jet printing ink, the color is bright, colorful, color gamut broad.
