Title:
DELAY CIRCUIT AND DRIVE DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/186471
Kind Code:
A1
Abstract:
A delay circuit and a drive device, wherein the delay circuit may comprise at least two branches, the at least two branches are connected in parallel, and each of the at least two branches has a different delay; and the delay circuit comprises at least one register, and the register is used to control one of the at least two branches to turn on so that the delay circuit generates a delay corresponding to the branch that is turned on. The greater the delay of an input signal, the smaller the slew rate. Therefore, the slew rate of the input signal traversing any one of the at least two branches is different. By means of the at least one register controlling one of the at least two branches to turn on, the slew rate of an output signal may be adjusted so that the slew rate of the output signal may be compatible with different protocols or different modes under the same protocol.
