Title:
CLASS-A AMPLIFICATION APPARATUS
Document Type and Number:
WIPO Patent Application WO/2023/061387
Kind Code:
A1
Abstract:
The present invention relates to a class-A amplification apparatus, in particular to a class-A amplification apparatus which is connected in series in a circuit by using an energy source, is used for eliminating a cut-off of a fully controlled device, and has a high energy efficiency to satisfy a high-dynamic class-A output. The apparatus comprises devices for amplification, wherein the devices comprise a first device and a second device, the first device and the second device forming a push-pull amplification circuit; and the apparatus further comprises a diode and an energy source, wherein first electrodes of the devices and second electrodes of the devices are connected to the energy source in series, and the diode is connected to the energy source in parallel. The present invention has a rational design, and has the advantages of being convenient to implement, high energy efficiency, and the large dynamic range of a class-A output.
