Abstract

The invention provides an array amplifier based on frequency detection, the array amplifier includes several sub-amplifiers, the several sub-amplifiers are in one-to-one correspondence with the several sub-detectors in the array detector, and all of the several sub-amplifiers include an LC feedback resonance structure; The LC feedback resonance structure is used to select a signal of a specific frequency from the received signal, so that the frequency of the signal selected by each sub-amplifier is different from the frequency of the signal selected by other adjacent sub-amplifiers. The technical scheme of the present invention improves the amplifier circuit by using the LC feedback resonance structure to make the frequencies to be detected of the output electrical signals of each sub-amplifier in the array amplifier inconsistent, avoiding mutual interference between the sub-amplifiers, and reducing the difficulty of data processing. Functionally, the independent detection of each sub-detector and sub-amplifier is realized.

Description

technical field [0001] The invention relates to the field of amplifiers, in particular to an array amplifier based on frequency detection. Background technique [0002] The current array amplifiers are densely arranged, and the output signals of each amplifier have the same frequency. In this way, during frequency detection, the frequency signal of a certain detector will radiate out, causing interference to surrounding detectors, so that the surrounding detectors cannot realize independent detection functions. Contents of the invention [0003] In order to avoid crosstalk between array amplifiers in the frequency detection process, the present invention provides an array amplifier based on frequency detection. [0004] In the array amplifier based on frequency detection provided by the present invention, the array amplifier includes several sub-amplifiers, and the several sub-amplifiers correspond to the several sub-detectors in the array detector one by one, and all of ...
