Abstract A biasing circuit includes a reference current source, a first transistor, a second transistor, and a voltage buffer. The first transistor includes a first connection end coupled to the reference current source, a control end, and a second connection end coupled to a system grounding end. The second transistor includes a control end coupled to the control end of the first transistor, a first connection end coupled to a system power supply end, and a second connection end coupled to the system grounding end. The voltage buffer includes an input end coupled to an output end of the reference current source and the first connection end of the first transistor, and an output end coupled to the control ends of the first transistor and the second transistor. The first transistor and the second transistor constitute a current mirror.
