This application claims priority under 35 USC 119(a) to Korean Patent Application No. 10-2021-0167273 filed on Nov. 29, 2021 and Korean Patent Application No. 10-2022-0042073 filed on Apr. 5, 2022 in the Korean Intellectual Property Office, the disclosure of each of which is incorporated herein by reference in its entirety.
The present inventive concept relates to an offset detector circuit for a differential signal generator, a receiver including the differential signal generator, and a method of compensating for an offset of the differential signal generator.
Electronic devices include various functional blocks or devices configured to provide various functions. Various functional blocks or devices may transmit and receive data to and from each other through transmitters and receivers.
The above and other aspects, features, and advantages of the present inventive concept will be more clearly understood from the following detailed description, taken in conjunction with the accompanying drawings, in which:
FIG. 1 is a diagram illustrating a receiver according to an example embodiment;
FIGS. 2A to 2D are diagrams illustrating an offset compensation method of a differential signal generator;
Hereinafter, various embodiments will be described in detail with reference to the accompanying drawings.
FIG. 1 is a diagram illustrating a receiver according to an example embodiment.
Referring to FIG. 1, a receiver 100 may include a differential signal generator 110, an offset detector circuit 120, and an offset compensator 130.
