Embodiment Construction

[0101] In order to make the purpose, features and advantages of the present invention more comprehensible, specific embodiments of the present invention are listed below, together with the accompanying drawings, for detailed description as follows.

[0102] Certain terms are used in the description and claims to refer to particular elements. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. The specification and claims do not use the difference in name as a way to distinguish components, but use the difference in function of components as a criterion for distinguishing. The words "comprising" and "including" mentioned throughout the specification and claims are open-ended terms, so they should be interpreted as "including but not limited to". The term "approximately" means that within an acceptable error range, those skilled in the art can solve the technical problem within a certain error range and ...

Abstract

An electronic device is provided. The electronic device is used for detecting an antenna element. The electronic device further comprises a sensing circuit, a comparison circuit, an interface circuit,an internal low-noise amplifier, a bypass path and a selection circuit. The sensing circuit generates a sensing potential according to an input current, wherein the input current is associated with the antenna element. The comparison circuit compares the sensing potential with a first reference potential to generate a first control potential; the sensing circuit is coupled to a radio frequency node through the interface circuit, and the interface circuit is used for reducing mutual interference between the antenna element and the electronic device; the selection circuit selectively couples the internal low noise amplifier or the bypass path to the radio frequency node according to the first control potential. The electronic device at least has the advantages of simple structure, low manufacturing cost and the like, so that the electronic device is very suitable for being applied to various mobile communication devices.

Description

technical field [0001] The invention relates to an electronic device, in particular to an electronic device capable of automatically detecting the type of an antenna. Background technique [0002] With the development of mobile communication technology, mobile devices have become increasingly common in recent years, such as portable computers, mobile phones, multimedia players and other portable electronic devices with mixed functions. In order to meet people's needs, mobile devices generally have a wireless communication function. Some cover long-distance wireless communication ranges, for example: mobile phones use 2G, 3G, LTE (Long Term Evolution) systems and their frequency bands of 700MHz, 850MHz, 900MHz, 1800MHz, 1900MHz, 2100MHz, 2300MHz and 2500MHz for communication, while Some cover short-range wireless communication ranges, for example: Wi-Fi, Bluetooth systems use 2.4GHz, 5.2GHz and 5.8GHz frequency bands for communication, or GPS (Global Positioning System) syst...
