  • Power supply current detection circuit and its control method, device, amplifier and storage medium
    Patent number: 11543439
    Abstract: The current detection circuit includes a signal amplification branch, a first voltage branch, a second voltage branch and a first feedback circuit branch. The first feedback branch generates a feedback signal according to the first voltage generated by the first voltage branch, the second voltage and the first reference voltage generated by the second voltage branch. The signal amplification branch generates a first amplified voltage according to the first voltage and the feedback signal, and generates a second amplified voltage according to the second voltage and the feedback signal. The first voltage branch generates a first voltage and a first output voltage according to the first input voltage and the first amplified voltage. The second voltage branch generates a second voltage and a second output voltage according to the second input voltage and the second amplified voltage.
