摘要： A bias circuit includes a transistor having a control gate, a first terminal and a second terminal coupled to a ground level, a first resistor coupled to the control gate, a first capacitor coupled between an input signal and the first resistor, a diode coupled between a connection point of the first capacitor and the first resistor, and the ground level, a second capacitor coupled between the control gate and the ground level, a second resistor coupled between the control gate and the ground level, a third resistor coupled between the control gate and a predetermined voltage, a fourth resistor coupled between the predetermined voltage and the first terminal, and a fifth resistor coupled between the first terminal and a bias signal. A current through the transistor corresponds to the input signal, and the bias signal is generated according to the current through the transistor.
