Description

technical field

[0001] The invention is suitable for a current mode high-fidelity power amplifier and belongs to the technical field of electronic audio. Background technique

[0002] It has been more than a hundred years since Edison invented the phonograph in 1877. The first 70 years of audio development was slow and stuck in an ivory tower. It was not until 1927 that Bell Laboratories invented the epoch-making negative feedback (NFB) technology that high-fidelity power amplifiers entered the stage of history. With the innovation of electronic devices and the continuous improvement of circuit forms, the performance of high-fidelity power amplifiers has been continuously improved. In the past, people used CDs to listen to music, and the performance of traditional high-end high-fidelity power amplifiers can meet the requirements.

[0003] According to the difference between the high and low impedance of key nodes in the circuit, the traditional high-fidelity power amplifi...
