Abstract: A control circuit with a bypass function includes a first signal terminal, a second signal terminal, an output terminal, a first switch unit to a fourth switch unit, an output switch unit and a bypass unit. The first signal terminal is used for receiving a first signal. The second signal terminal is used for receiving a second signal. The first switch unit is coupled to the first signal terminal. The second switch unit is coupled between the first switch unit and the output switch unit. The third switch unit is coupled to the second signal terminal. The fourth switch unit is coupled between the third switch unit and the output switch unit. The output switch unit is coupled between the second switch unit and the output terminal. The bypass unit is coupled between the first switch unit and the output terminal to provide a bypass path corresponding to the first signal.

Abstract: A bias circuit includes a first transistor, a second transistor, a first resistor and a second resistor. The first end of the first transistor is coupled to a first voltage source. One end of the first resistor is coupled to the second end of the first transistor, and the other end of the first resistor is coupled to the control terminal of the first transistor. The first end of the second transistor is coupled to a second voltage source, and the second end of the second transistor is coupled to the control terminal of the first transistor. One end of the second resistor is coupled to the other end of the first resistor, and the other end of the second resistor is coupled to the control terminal of the second transistor.
