Abstract

The invention relates to a transistor amplifier based on diode feedback, and the transistor amplifier comprises a three-terminal transistor which comprises a control end and an output end; and a feedback circuit electrically connected between the control end and the output end, wherein the feedback circuit comprises a diode.

Description

technical field [0001] The application belongs to the field of electronic circuits, in particular to a transistor amplifier, chip and electronic equipment based on diode feedback. Background technique [0002] Stability has been one of the most difficult problems in amplifier design in the field of electronic circuits for many years. In order to solve the stability problem of the amplifier, various negative feedback techniques are generally adopted in the industry at present. Such as resistance feedback, capacitance feedback, resistance capacitance RC feedback, source resistance feedback and so on. [0003] Among them, the feedback technique of the source string resistor usually sacrifices efficiency. The inventors of the present application found that when the output power fluctuates greatly, the power amplifiers using the other three feedback methods have large signal distortion when the power output is large, the transmission characteristics are not stable, and the line...
