Control method, device, electronic equipment and storage medium of digital time converter

Abstract

The embodiment of the invention provides a control method, a device, an electronic equipment and a storage medium of a digital time converter, the method comprises the steps of: obtaining input control information, which comprises multiple pieces of subcontrol information; converting the control information into coordinate information of a capacitor; acquiring capacitance information of corresponding coordinates based on the coordinate information, wherein the capacitance information comprises capacitance values; obtaining total capacitance information according to the capacitance information, wherein the total capacitance information comprises a total capacitance value; and responding according to the total capacitance information. According to the control method, the device, the electronic equipment and the storage medium of digital time converter, nonlinearity of a digital circuit which uses binary control information only to control the capacitor can be reduced since the binary control information portion is converted to thermometer coded information.

Description

technical field [0001] The present invention relates to the technical field of digital circuits, in particular to a digital time converter control method, device, electronic equipment and storage medium. Background technique [0002] At present, digital circuit modules such as all-digital phase-locked loops (ADPLL), clock and data recovery (CDR) and direct phase modulators in polar or out-of-phase transmitters are often used in the field of digital circuits, while digital time converters ( DTC) plays a key role in these blocks, and the phase error of DTC affects the spectrum and error vector magnitude of the transmitter as well as the phase error of the ADPLL and CDR circuits. Therefore, DTC with high resolution and high linearity has been a research hotspot at home and abroad. For example, the main cause of ADPLL's fractional spurs is the non-linearity of DTC, so a high linearity DTC can effectively reduce ADPLL's fractional spurs. [0003] At present, if DTC is used to a...
