DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

The present invention is particularly described with the following examples, which are merely for illustration. For those skilled in the art, various modifications and refinements can be made without departing from the spirit and scope of this disclosure. Therefore, the scope of protection of this disclosure shall be defined by the appended claims. Throughout the specification and claims, unless clearly specified otherwise, the meaning of “a” and “the” includes “one or at least one” element or component. In addition, as used in the present invention, unless it is clearly apparent from the context that the plural is excluded, the singular also includes the plural elements or components. Additionally, when used in this description and all the following claims, unless clearly specified otherwise, “therein” can mean “in” and “on”. The terms used throughout this specification and claims, unless specifically noted, usually have their ordinary meanings in the field, in the context of this disclosure, and in the specific context. Some terms used to describe the present invention will be discussed below or elsewhere in this specification to provide additional guidance to a practitioner regarding the description of the present invention. Any examples given anywhere throughout the specification, including the use of any terms discussed herein, are merely for description and do not limit the scope and meaning of the present invention or any exemplified terms. Likewise, the present invention is not limited to the various embodiments proposed in this specification.

Furthermore, if a term “coupled” or “connected” is used herein, it includes any direct and indirect electrical connection measures. For example, a text describes that a first apparatus is electrically coupled to a second apparatus, meaning that the first apparatus may be connected to the second apparatus directly or indirectly via through other apparatuses or connection measures. Additionally, if a description involves transmission or provision of electrical signals, those skilled in the art should understand that the transmission of electrical signals may be accompanied by attenuation or other non-ideal changes, but unless specifically stated otherwise, the electrical signals transmitted or provided from sources to receiving ends should be considered as substantially the same signal. For example, in a case that an electrical signal S is transmitted (or provided) from an endpoint A of an electronic circuit to an endpoint B, where it may pass by the source and drain terminals of a transistor switch and/or a possible stray capacitor, causing a voltage drop, but if the objective of such design is not to intentionally use the attenuation or other non-ideal changes during transmission (or provision) to achieve certain technical effects, the electrical signal S at the endpoint A and the electrical signal S at the endpoint B of the electronic circuit should be considered substantially the same signal.

It can be understood that the terms “comprising,” “including,” “having,” “containing,” “involving,” and the like as used herein are open-ended, meaning inclusion but being not limited thereto. Additionally, any embodiment or claim of the present invention does not have to achieve all the objectives, advantages, or features disclosed in the present invention.
