A pseudo resistor with tunable resistance including a first transistor and a second transistor is provided. The first transistor has a first terminal, a second terminal and a control terminal. The first terminal of the first transistor serves as a first terminal of the pseudo resistor. The control terminal of the first transistor receives a control voltage. The first transistor is controlled by the control voltage, such that the first transistor operates in a weak inversion region. The second transistor has a first terminal, a second terminal and a control terminal. The first terminal of the second transistor is coupled to the second terminal of the first transistor. The second terminal of the second transistor and the control terminal of the second transistor are coupled to each other to serve as a second terminal of the pseudo resistor with tunable resistance. The second transistor operates in the weak inversion region.
